[macOS] VideoPlayer.clockTime gets stuck for a few frames when starting to play a video
Reproduction steps:
1. Open attached project "VideoPlayer_Bug_Report" and load Scene "VideoScene"
2. Enter Play Mode
3. In the Game window check "Log On Update"
4. Click "Prepare", "Seek to frame 100", "StepForward" and "Play" in this order
5. After a couple of frames of the video play, exit Play Mode
6. Observe the Console output immediately after the button "Play" was pressed
Expected result: VideoPlayer.clockTime starts updating immediately after VideoPlayer.isPlaying is set to True
Actual result: VideoPlyaer.clockTime starts updating only after a couple of frames pass

Resolution Note:
VideoPlayer.clockTime keeps the same value across calls when called more frequently than the clock's resolution. Also, MonoBehaviour.Update may get called faster than the movie frame rate, which explains why not every call will show a new video frame.
