When scrubbing, make the timeline progress match exactly to the cursor position. Also, set the timestamp to match that progress. Both are not allowed to change until the scrub completes. This makes the UI stable while scrubbing after the end of the media data in subsequent commits that jump the time to the duration at EOS.
