Ability to control the embedded video viewer of attachement

When watching a video attachment, I can't scroll back or forth in time to skip parts of the video, only to watch the WHOLE thing.

For example, the window loaded again for some reason- I had to re-watch 10 mins I already saw before :(

 

Would be amazing (actually, needed. it's not much of a "nice to have" ;) to be able to control the video time so I don't have to watch the whole thing and can skip back and forth when needed for clarification.
