Every locale formatter takes the language as an argument. Under the React
Compiler a formatter that read the i18n singleton was memoized on its other
arguments, so a card kept "2 hr 4 min" after a switch to Hungarian; plexLang()
had the same flaw and left Plex queries in the old language. Components now
take the language from useTranslation, and the signature makes forgetting it
a type error.
- ratings, file sizes, stream stats: the language's decimal mark ("8,3")
- view and subscriber counts compact in the language ("1,2 E")
- seconds as the language's unit ("6 mp") in the sliders and the stats
- a person's birth and death dates as dates, not ISO strings
- A-Z lists by the shown name in the language's alphabet (compareText),
the tag catalog re-sorted by its translated names
- lint local/locale-format (was date-format) also refuses Intl.NumberFormat
outside lib/format.ts, localeCompare, and a component reading the language
off the i18n singleton
Tags A-Z as in-place checks (the menu stays open for the next); Priority
as the fixed steps 10 5 3 2 1 0, an off-scale current value ticked in its
place. A pick re-sorts the list at once, moving only that row
(placeByPriority, the server's order), and the table / card pager and
the focus follow it (DataTable and useCardPager take a reveal seq,
listNav.focusNavItem lands on the row's own "…", a virtualized card
revealed first). ActionMenu rows take check: many | one. The menu reads
the row fresh from the cache and keys its target by id.
Deep review of the debt burn, each measured in Chrome:
- Back from a sub-view whose focused control the swap removed: the focus keeper put the focus on a
stand-in (the returning list's first item) and `restoreNavPosition`, finding the focus "already
somewhere", gave up — Plex show → Back landed on tile 0, not the tile it was opened from. A
stand-in the keeper placed now counts as untouched, like <body>. The keeper's walk up also stops
at its container: a slot left with nothing focusable no longer sends the focus to the first
control of the whole document.
- DataTable enabled both layouts' keyboard lists with the same flag, and `useListNav` reads its ref
only when the flag changes: after a resize across `md`, the layout that mounted was never
registered (no j/k) and the one that left stayed registered. Each is enabled with its layout.
- A Plex playlist nests blocks and each show's episodes in one DndContext; closestCenter and the
keyboard coordinates weighed every droppable, so a movie landed "over" an episode — announced as
a place in the other list, dropped somewhere else or nowhere. `sameListCollision` and
`sameListKeyboardCoordinates` keep a drag among its siblings; onDragEnd's episode → block
resolution is gone with the case.
- dnd-kit reports the item over itself in the pick-up's own tick; announced, "moved to position 1"
replaced "picked up … use the arrow keys" before a screen reader read it.
- "A page with a sticky ColumnHead must declare fadeTop: false" lived in
prose: a registry flag on three pages plus an App special case for the
Channels card layout, and the next table page would have re-acquired the
fade-on-the-header defect with every lane green. ColumnHead now registers
itself with the enclosing PageScroller (ui/stickyTop) while mounted; the
registry flag, the App branch and the prop plumbing are gone. Measured on
localdev: the top mask is 0px under Channels' and Audit's headers, 20px on
Home and the Feed.
- ui/DataTable mounted its table AND its card list at every width, one
hidden by CSS: double DOM and render cost, duplicate ids, two keyboard
copies of every row. It now mounts the one the `md` media query calls for
(lib/useMediaQuery); the keyboard test asserts one layout at each width.
- The Plex module's content width went px → rem with the rest of the page.
Third and last slice of the E11 keyboard layer (S4c). S4a/S4b covered every card grid and rail; the
table-shaped pages — the channel manager, a playlist, the download center — were still Tab-stop
country: a channel row carries a priority stepper, four action buttons and a tag picker before the next
row's name.
- `ui/DataTable keyboardNav`: the rows are the items, Enter clicks the element a column marks
`data-nav-open`. DataTable renders its rows twice (a table, and a card list below `md`); both register
and `lib/listNav` now walks only lists on screen (`checkVisibility`), so `j` past the last row never
carries on into the hidden copy.
- `lib/listNav` leaves a key something before it already handled (`defaultPrevented`): during a keyboard
drag a playlist row's grip moves the row with the arrows, and dnd-kit takes the key on the document
before listNav's window listener. Without the guard ↓ moved the focus off the grip and dropped the drag.
- `ui/NavGrid as="tbody"` for a table whose body is the list (the playlist, under dnd-kit's
SortableContext).
- Wired: Subscriptions and Discovery tables, the card layout (`ChannelLayoutGrid` → VirtualGrid
`keyboardNav`), Hidden/Blocked cards (the ChannelLink name is a channel's open element); a playlist's
rows (the title plays; the grip keeps Space/Enter); the download queue, library and shared lists (the
play button opens, `IconBtn open`; a row without one opens nothing).
- `listNav.wiring.contract.test`: `VirtualGrid` and `DataTable` must say `keyboardNav` like `Carousel`,
`DownloadRow` is a card; the audit log's table is the one exemption (its rows open nothing), and an
exemption that no longer matches a tag fails the test.
Measured in Chrome: Channels table j → row, ring round the whole row; a row walked down keeps 12px above
the viewport edge, walked up clears the sticky header by 35px; Enter opens the channel. Cards 3 columns:
→ 0→1, ↓ 1→4. Hidden and Discovery: j + Enter open the channel. Playlist: j + Enter plays, Escape returns
focus to the row; a keyboard drag (Enter on the grip, ↓) moves the row with focus kept on the grip, and
Escape cancels with the order unchanged. Downloads library: Enter plays a video row, does nothing on a
plain file row.
