Ten tests, five of which fail on the build before this. The desktop
guard is meant to pass there -- that is its job, and it is the one that
caught a three-pixel regression nothing else could see.
`openTheQueue` moves to the fixtures, because hiding one button failed
ten tests in four files about the back stack and about layout: every
one of them opened the queue by clicking `#queue-button`, and so was
quietly asserting *which* route exists as well as what the queue does.
The route differs by width now and that is the feature.
Two smaller things. The play button is named for its action, so an
exact 'Play' waits out a fixture track -- 11.1s per test, passing by
luck, and it would have failed outright against LONG_TRACK. And the
"nothing playing" case clears the queue itself rather than trusting the
app not to have played anything: `make e2e` runs one long-lived app
across every spec (#168), which is how a deterministic bug first showed
up as a flake.
Nine tests, and the header says which of them reproduce the defect:
three do, and the other six cannot. "The entry is not orphaned" and "a
docked column is not in the stack" are both vacuously true of a build
that pushes no entry at all. That was established by reverting the
source and re-running, not assumed.
The containment assertion is the one worth reading twice. It asks
where the panel *is* rather than whether a menu is clipped, because
CI's Chromium and WebKit both have the Popover API -- so the symptom is
invisible here and a spec asserting "not clipped" is green on the
broken build. `.planning/NOTES.md` states the mechanism.
The rest assert the entry rather than `aria-expanded`, which is the
shell's own bookkeeping and was right throughout the defect: what has
to be true is that one back press closes the queue and the *next* one
navigates.
