Subject: [PATCH] fix: update the progress-bar correctly when pausing the video
 and click the seek-bar. First,when handle mosue down event of the seek-bar,
 we set player's scrubbing_ to true, and at the same tick, the update function
 called and we call super.update(). however, it returns undefined because the
 progress equals to the previous progress, the root cause is that we get
 cached currentTime. So we call super.update() in the next tick to make sure
 we can get the correct progress.Second, when toggle visibility of the
 document,we should not call this.enableInterval_() when the player is paused
 or waiting. Fixed https://github.com/videojs/video.js/issues/6232
