Timo fd42de365a fix(extension): keep the chosen tab selected when activation fails
Selecting a tab and reopening the popup showed no target again. The selection
only ever existed as currentTabId, which means "the tab we successfully
injected into". Any activation failure — a player frame needing host access, a
page still loading, a document that navigated mid-injection — cleared it, so
the user's choice disappeared along with the failure.

The choice is now stored in its own right, persisted before activation starts
and kept across a failed one. GET_STATUS reports it as targetTabId with a
terminal state next to it: ready, activating, access_required or error, plus
the underlying message. The popup already highlights targetTabId, so the tab
stays visibly selected and can explain itself instead of silently vanishing.

Nothing retries on its own. Reactivation happens only when the user selects
again or grants the missing host access, which is what turned the previous
attempt at this into an endless reinjection loop on every popup open.

Extension E2E smoke tests

Browser-level tests for the parts that unit tests cannot reach: which <video> the extension picks on a real page, and whether the packed extension gets far enough to control it.

npm run test:e2e:install   # once, downloads the browsers
npm run build:extension    # extension.spec.mjs loads dist/chrome
npm run test:e2e

Layout

Path Purpose
detection.spec.mjs Runs the shipped findVideo() against the fixture pages
extension.spec.mjs Loads dist/chrome, injects into a tab, applies remote play/pause/seek
fixture-server.mjs Static server for the fixtures, with byte-range support for media
fixtures/pages/ One page per scenario
fixtures/media/ Small generated clips (see below)
helpers/content-source.mjs Lifts the real finder out of extension/content.js

Two rules worth keeping

The specs run the shipped source, not a copy. helpers/content-source.mjs extracts findVideo and its ranking helpers straight out of extension/content.js. A fixture that passes against a reimplementation would prove nothing about the extension. If you split the finder into more functions, add them to VIDEO_FINDER_EXPORTS there and to VIDEO_FINDER_PARTS in scripts/test-content-video-finder.cjs, or the extraction fails loudly.

Each fixture marks its own answer. The element that must win carries data-expected; videos that have to be playing carry data-autoplay, and ready.js holds the page back until metadata and playback have settled. The specs assert those preconditions before judging the finder, so a broken fixture reads as a broken fixture instead of a scoring regression.

Scenarios

Fixture What it pins down
simple-player.html The ordinary case
iframe-player.html Player inside a same-origin frame, empty top document
late-frame.html Player frame attached after the page settled
shadow-player.html Player in a shadow root, tiny teaser in the light DOM
muted-player.html Mute must not disqualify the only player
hidden-preload.html A display:none preload still reports 1080p; it must lose
ad-frame.html 1080p asset in a 300x250 ad slot must lose to the real player
background-loop.html Silent looping hero must lose despite being the largest
multi-player.html Between equal players, the playing one wins
sourceless.html A large <video> with no source can never be the player
nested-frame.html Player two frame levels down
reloading-frame.html Frame that swaps its document, with no mutation in the top one

Benchmark

bench-finder.mjs is not a spec, because timings are machine dependent and would only add noise to CI. Run it by hand when the finder changes:

node tests/e2e/fixture-server.mjs 4173 & node tests/e2e/bench-finder.mjs

It measures the shipped finder (lifted from content.js) against the pre-v3.1.0 formula, which is transcribed inside the script since that code no longer exists in the tree.

Regenerating the media

Solid-colour clips, a few KB each, committed so the suite needs no network:

ffmpeg -y -f lavfi -i "color=c=blue:s=1920x1080:d=30:r=10" -c:v libx264 -preset veryfast -crf 45 -pix_fmt yuv420p -movflags +faststart fixtures/media/player-1080p-30s.mp4

Same command with green/854x480/12, red/640x360/5 and gray/1280x720/3 for the other three.
