Steps to reproduce:
1. Open attached project "VideoPlayerTimescaleTest.zip"
Inside there is a video that just shows frames and time passed
2. Make sure VideoController script is active and it sets VideoPlayer.skipOnDrop to false
3. Set PlaybackSpeed to a higher value like 3 or 6 to make sure the video endures some lag
4. Enter Play mode and observe Frames and time from VideoPlayer object not match the ones in the video.

Expected: VideoPlayer.frame and VideoPlayer.time should return the actual time of the video and not projected values
Actual: vp.frame and vp.time run their course regardless of what the video is showing, reach their end/loop point before the video is finished
