Describe the bug

In Visual mode, vertical videos overlay their video block causing display issue, making the caption underneath hard to read and even overflowing to the toolbar and the next block.

We also lose the cover image that was previewing the video, for all type of videos.

Those are regressions for Android as they were not present in v1.19.

To Reproduce
Steps to reproduce the behavior:

1. Add a video block
2. Upload a vertical video
3. Focus the video block
4. See the display issue, still visible even after focusing another block

Expected behavior
I'd expect the video to not be displayed at all on focus
