Summary [HTMLMediaElement] Reschedule timeupdate event if fired too early

Reported 2024-09-03 05:34:15 PDT
HTMLMediaElement fires 'timeupdate' every 250ms in repeating timer. If the timer is fired before 250ms from the last occurrence, it is silently skipped and needs to wait for another 250ms. As a result, the gap between two following timeupdate events may vary 250-500ms. This may happen in two cases: 1) Non-periodic timeupdate event is scheduled for any reason. 2) When the difference between two timer calls is lower than 250ms. This may happen when there are multiple timers to handle at the same time in ThreadTimers (maxDurationOfFiringTimers). See: https://github.com/WebPlatformForEmbedded/WPEWebKit/pull/1392
