Closes 5000: AutoPlay in Floating Player only works one time
Factor out the code that queries the recommendation. It needs to be called in two places:
(1) `RecommendedContent` - need to cover the case of floating player + visit another video page.
(2) When video is floating and autoplayed the next video.
## Issues
5349: Remove theater mode button from player in comments
5519: Theatre mode button doesn't do anything in full screen mode [Odysse/LBRY desktop app]
## Notes
5349: Wanted to hide for 'markdown' as well, but it seems useful for 'markdown' (to clear the screen from Related), so I did not include it.
## Issue
5438: Keep floating player in view area
## Changes
- Restore correct z-index
- The bug came as a side effect of cbac2174. Redo cbac2174 to cover both close button and floating player.
- Remove wobbling when dragging to bottom-right.
- The extra gap introduced is fighting against react-draggable. If gaps are needed, handle it entire ourselves or do it somewhere in react-draggable; neither is worth the effort, so the gap was removed.
## Issue
The previous code only handled the clamping if the FP is already floating when the main window is resized.
1. In fresh Odysee session, the floating player is always clipped on the right.
2. If you resize the desktop while not floating, the FP could be clipped when you go into floating mode.
## Changes
- Factor out the clamping code.
- Add another effect to handle 'isFloating' changes.
## Issue
4741: `Pop out player disappears or is cut off`
## Approach:
- When dragging stops, determine the location of the floating player with respect to the main window in terms of percentage.
- When window is resized, roughly re-position based on the stored percentage.
## Issue
Fixes 4709 `Dragging floating player via video section pauses video`
## Changes
Don't propagate the key-up action if the window was dragged. Hopefully there isn't another sub-component that relies on the action being propagated.
## Note
If you drag at exactly the "Play" icon the control bar, the issue still happens.
