When a text track cue is added to a track after its time interval has already passed during media playback, it is considered a "missed cue". In this scenario, the cue's `onenter` and `onexit` events should not be fired. This change introduces a new Web Platform Test to confirm this behavior. The test plays a video and, after a delay, adds a cue whose time range has already elapsed, asserting that no events are triggered. Bug: 448906517 Change-Id: Idaf392d24f9c4737e2abbd57c02a0e82848569a1
