This test plays ~1.5 seconds of a video with internal cues, seeks back to 0.3, and checks the style of the cue that should be visible at that time. When it fails, there isn't a visible cue because the media engine hasn't delivered a cue for that time, I believe because of startup latency.

Created attachment 245632 [details] Proposed patch. Introduce a brief pause between receiving the 'seemed' event and checking caption style to allow for media engine latency.
