A direct-played file's own subtitle stream (WebKit lists an mp4's mov_text) was switched to hidden and drawn under any choice, Off included: only the player's <track> is kept hidden and read, other subtitle tracks are switched off. The lift was measured in screen pixels and applied inside the x1.25 windowed player, and re-measured off a box carrying its own (or a mid-slide) transform: an untransformed outer box is measured, the distance divided by the scale, and a cue that just appeared is placed, not slid from where the last one was left.
On an iPad the bar covered the text whenever it was up: the browser places a
native cue by its line, which nothing animates. The track now stays loaded as
hidden and PlexSubtitles draws the active cues, measured against the bar and
lifted above it in 200 ms, back down when it hides. The viewer's size, colour,
background and outline settings style the text directly. Also fixes a test
typing slip from the search pill change.
