Bug description

When viewing an MP4 video from Safari in iOS - fullscreen playback results in non-fullscreen behavior. In portrait orientation, fullscreen moves the windowed video up in the browser, but retains the header and footer. When switched to landscape, the video is just a thin black box, and again the header and footer is retained.

Behavior is the same both logged in to NextCloud and via a public share link.

Steps to reproduce

1. Upload an MP4 video
2. Create a public share link
3. Access the link from Safari on iOS
4. Click fullscreen, and then rotate to landscape

Expected behavior

The video should expand to fullscreen completely, without the header/footer from nextcloud and with the video correctly centered and scaled on the device
