rsvp-controller.test.ts calls controller.start() in ~20 tests but never stops
the controller. start() schedules a countdown (setInterval, 500ms x3) that then
schedules the recurring word-advance (setTimeout). On the real clock those fire
~1.5s later — after the test file's jsdom env is torn down — and
emitStateChange's dispatchEvent(new CustomEvent(...)) runs against a stale realm
and throws. Vitest reports it as an unhandled error and fails the whole run
intermittently on CI:
TypeError: Failed to execute 'dispatchEvent' on 'EventTarget': parameter 1 is
not of type 'Event'.
at RSVPController.advanceToNextWord -> emitStateChange (Timeout._onTimeout)
Fake only the timer functions (setTimeout/setInterval + their clears) for this
suite via vi.useFakeTimers({ toFake: [...] }); useRealTimers in afterEach
discards any still-pending fakes. The tests assert synchronously and never
advance playback, so faking the timers changes no assertion; Date/performance
stay real so CFI/position checks are unaffected. Test-only; production behaviour
is unchanged.
