Video should never be cropped when page is scrolled to the top

[ThiefMaster]

This is an annoyance on media.ccc.de and many other media sites that are not YouTube.

I pretty much always have my Firefox window maximized (on 1440p resolution). Unfortunately, due to the large video title and speaker names above the actual video (YT has them below), this pushes the video down far enough so for every video I'm watching I carefully need to scroll down to see the full video.
