Modal takes a required initialFocus (field / close / action), a field that
loads late takes the focus while it still rests on the close button, and
ModalFooter portals a dialog's commit row under the scrolling body from any
depth. The header and footer fades follow the body's scroll timeline, and the
viewport's interactive-widget=resizes-content keeps the footer above an
on-screen keyboard.
- SelectTrigger lays its toolbar value out as a row; the saved-view chip passes its glyph and
modified dot through the icon/trailing slots (an <svg> is display:block and broke the chip in two).
- One Escape in a dialog's open list closed the list AND the dialog: the list's close flushes
synchronously and pops its layer before the dialog's window listener runs. takeEscape() is the one
close-on-Escape test (topmost AND not yet taken); Modal, the Welcome lightbox and useLayer use it,
and keymap.dispatch ignores a taken Escape.
- /watch: the Download sits on the toolbar rung, level with the Repeat chip.
Deep-review of E11 (19 raised, 14 confirmed; 2 refuted, 3 latent test-hardening notes dropped).
- Back from a sub-view (a Plex show page, a Messages thread) restores the item it was opened from
even when focus was still inside the view: the first attempt now waits one task, past the
sub-view's own popstate listener (measured in Chrome: it left focus on <body>).
- The restore listener is installed at load, so the first Back after a reload finds it; a push
cancels a restore still waiting for the last landing's lists.
- Navigating over an overlay asks it again, a render apart, while its entry stays: the Plex
player peels one panel per Back step, so Shift+W over info + stats closed one panel and dropped
the navigation.
- j/k: a native <button> item keeps its own Tab stop; landing twice on the same item no longer
leaks its tabindex; after the focused item is removed (a hidden card) the next j goes on from
its slot when that slot is on screen.
- An abandoned `g` no longer swallows a modifier chord (g, then Mod+K opened the browser search).
- A hover card above a dialog no longer switches its Tab trap off (player, Modal, wizard,
Lightbox): new layerStack `anyBlockingLayerAbove`.
- "Manage views…" closes its menu before opening the dialog, through a shared `closeThenAct`
that ActionMenu now uses too.
- Copy: the EN welcome says "Feed"; the EN unreachable reason no longer claims a change;
stale comments about PlayerModal's scroll lock and dialog contract.
Round 6 widened dialog focus ownership to count focus inside ANY `aria-modal` subtree as ours, so a
dialog and the dialog stacked on it closing together would still hand the focus back. That clause has
no way to tell a layer closing WITH us from one that stays open, so a dialog closing on its own — an
in-flight mutation's `onSuccess`, not a click, since a scrim covers it — under a modal raised above it
pulled the focus onto its own pre-open trigger, behind that scrim, where Enter still activated it.
Three verifiers confirmed the mechanism and two corrected the severity down: it self-heals on the
next Tab, which is why this is a containment violation rather than a broken end state.
`lib/layerStack` cannot refine it. Measured against the real hook: at the instant the lower dialog's
focus cleanup runs, the both-closing case and the sibling-stays-open case give identical readings —
`anyLayerAbove` true, the upper layer topmost — because passive cleanups run parent-first and
`useDialogChrome` is declared before the effect that calls `removeLayer`. Gating on the stack turns
round 6's own test red. What separates them is the DOM: React detaches a deleted subtree before
passive cleanups, so a layer closing with us is already disconnected while one that stays open is
not. Both tests are green, and each was mutation-checked against the other.
Verified in Chrome on localdev: opening the cheat sheet from a sidebar button and closing it restores
that button; with the command palette stacked over the cheat sheet, closing the top one leaves the
focus neither on the background trigger nor on <body>, and closing both returns it to the trigger.
Welcome's Lightbox got the trap and the restore in round 6 but not the layer membership the other
shells have, so its Escape and Tab fired from a raw window listener whatever was on top — the shape
the wizard's comment records being bitten by, unreachable today only by a mount ordering nothing
enforces. It joins the stack. Its comment also read as though the four-shell sweep were finished:
`PlayerModal` is still an `aria-modal` surface with no name, no trap and no restore, which is on
ROADMAP.md now rather than implied to be done.
Round 5 extracted `ui/dialogFocus` so no shell would hand-roll the focus
contract, then introduced four ways to lose the focus anyway — all four measured
in jsdom against the real components.
**Ownership was narrower than the trap.** `ui/Modal` traps Tab over the whole
dialog on purpose, so a toast's Undo or ✕ stays reachable; ownership was tracked
over the panel alone. Tabbing to that ✕ therefore read as "the user left the
dialog", and since removing a toast fires no `focusin` to re-arm, closing
afterwards skipped the restore and left the focus on <body>. Before this hook
existed the restore was unconditional, so it was a regression.
**A dialog stacked above us is still ours.** A nested `ui/Modal` portals into its
own host, so it is outside the outer dialog's root however wide that scope is
drawn — widening alone could not fix it. Both closing in one commit left the
focus on <body>: the outer skipped its restore, and the child's own target (a
control inside the outer panel) was already detached, because passive cleanups
run parent-first. Ownership now means "inside my dialog, or inside a modal layer
above it", which is what the rule always intended.
**The wizard disagreed with `ui/Modal` on its first line.** `trapTab(e, panel)`,
with neither the dialog-root scope (so its own toast host was outside the cycle
— the connection notice never auto-dismisses, and its ✕ was unreachable from the
keyboard) nor the `container` argument the JSDoc exists for: `panel.contains(
panel)` is true, so focus sitting ON the tabIndex=-1 panel matched no branch and
a Shift+Tab walked into the app behind the scrim. Both call sites now pass the
same three arguments.
**The toast handover was a render-phase read-modify-write.** A `useMemo` read a
module global that the next line overwrote; React re-invokes a component body
and every `useMemo` factory in it on a StrictMode double render, and the LAST
invocation commits — so the second pass re-read what the first had just written,
the takeover host classified its OWN new toast as inherited, and the dev build
behaved exactly like the code round 5 replaced. Snapshotted through a ref keyed
on `isTop`, so a repeated invocation of one render is a no-op.
And the fourth `aria-modal` shell, `Welcome`'s screenshot lightbox, is finally
swept into the same contract: it declared itself a modal dialog while leaving
the focus on the thumbnail behind an 80%-black scrim and letting Tab walk the
landing page underneath.
The headline fix of the previous commit — StrictMode's re-mount taking the focus
off an `autoFocus` field — had no test at all; deleting it left all 1009 green.
It has one now.
9 tests, mutation-checked against 8 mutations, each red on the test that names it.
Deep-review round 3 of bug hunt 2026-09 (the round-2 overlay toast host, finished).
- Inside an overlay the toast stack sits above the bottom band (bottom-24, the UpNextCard rung) and
lets clicks between cards through: at the app's own spot it covered the Plex transport row and
PlayerModal's docked bar and took their clicks while a toast was up (measured: play/pause, ±10,
stop, prev/next, mute all hit the toast).
- ui/Modal and the onboarding wizard mount an overlay host too, so a toast raised under any dialog
is readable and a click on it no longer closes the dialog; the Modal's Tab trap spans the whole
dialog, so a toast's action and dismiss are keyboard-reachable. A test now enforces the
convention: a component that covers the viewport at z-overlay must mount <Toaster overlay />.
- PlayerModal's host moves into the stage in true fullscreen (outside the element holding the lock it
was painted under it).
- A host that takes over shows the toasts it inherits silently (no second role=alert, its region
aria-live=off until they are in), and each countdown bar starts as far in as its toast already is
instead of restarting while the real dismiss timer does not.
- The overlay-host registry uses lib/store instead of a hand-rolled listener triad.
The app HAS a platform layer -- AnchoredPopover (22 importers, with
arrows/typeahead/Escape/anchor-flip), QueryState (21), Modal (17),
PageShell, DataTable, Tabs, Tooltip and ~26 more -- but it sat flat among
~160 feature components with nothing marking it as one. Several of those
files describe themselves as 'the one place' or 'canonical' and were
still bypassed by hand-rolled markup, because a layer nobody can see is a
layer nobody uses; three separate inventory passes of this codebase
misread it the same way.
Moves the 33 domain-free modules into components/ui/, rewrites the
imports in 89 files, and makes the boundary a lint rule rather than a
convention: inside ui/ a one-level-up import (a feature component) and
any lib/api slice are errors. The rule was verified to fire on both and
to leave generic lib/ helpers alone. README.md states which side of the
line a component belongs on and why.
No behaviour change: 3x tsc, eslint, knip, prettier and 687 vitest tests
all green; no backend file touched.
