Floatplane: Add a buffer between top of video and search bar.

[micash41]

Every time that I watch a video on Floatplane I naturally will scroll my mouse wheel up. This is because as I am looking at the video player it appears as though the video may be getting cutoff. I know that I am not actually losing any image but its a weird look IMO to have the top of the video player directly against the search bar. Maybe consider adding just a few pixels of buffer to ease my insanity. I made used dev options to see what it would look like with 5px between the video and search bar and I think it is much better looking, but you could get away with even less. First image is with buffer (my version) , second image is without buffer(current version)
