In fullscreen, Next now keeps you there and shows nothing but the
picture: one video after another, no arrows, no header, no counter.
Three things had to change for that. The player was keyed on the video,
so every Next rebuilt the stage — and the stage is what is fullscreen.
It now survives, resetting its own per-video state instead of being
thrown away to get it.
The cleanup that ran on every change of source called exitFullscreen
outright. It exists for the Picture-in-Picture leak, which does need
handling per video; leaving fullscreen and dropping the source belong
to leaving the player, and are now only done there.
And resolving a stream set the source to nothing first, which unmounted
the element mid-fullscreen. The outgoing video is paused in place
instead, and the source goes straight from one address to the next.
The edge arrows are gone in fullscreen. The transport bar stays — it is
playback, not navigation — and fades on its own as before.
Also: Remove all downloads in the menu bar panel, which asks in the
window rather than in a panel that closes when you look away; and the
JavaScript round-trip logging is gone now that the scrape is settled.
Verified in the running app: three videos in a row without leaving
fullscreen, chrome faded to nothing, and Remove all reaching the
window's own "Delete every download?" with 50 downloads left untouched.
