## Ticket
1526: strange thumbnail size requested on mobile layout (pc only?)
## General Problem
It was trying to fetch based on the exact size of the video container, which would satisfy Core Vitals (in an overkill way), but would bring several issues:
- server-side caching would not work since everyone's window size is different in a responsive layout design.
- the additional 200ms wait for container size to settle down is not good (hardcoded wait time).
- the code did not account for device-pixel-ratio, so it's quite a futile effort.
Aside: In the past, we used to take the same image url as the tiles, so the video poster would appear immediately from due to browser cache, but the quality is bad because the tile requested a much smaller size.
The embed wrapper was not going through the CDN either as a null `containerRef` was passed in.
## Change
Removed the container-size check and just request for 1280x720. Reasons for this size:
- On average, that would be the ballpark of the final calculated value anyway for the average screen (+DPR consideration).
- That seems to be the current suggested thumbnail size in most recommendations.
- Our YT Sync is grabbing a much smaller size anyway.
* Bump react-draggable
Old version was giving out console errors for outdated react functions
* Refactor fileRenderFloating
* Merge fileRenderMobile into fileRenderFloating
* Fixes from review
* Attempt fix failed to view live
- Biggest change: Moved mobile player logic outside of fileRenderFloating into its own component fileRenderMobile, since there is no need for all that extra resizing and dragging code (for now, as mobile doesn't have a floating player)
- Moved player to the header height
- Removed rounded borders and margins
- Only pass necessary props
- Created new initialize play redux action
- Removed deprecated ~file app download~ keyboard functionality, moved preventDefault to videojs keyboard events to prevent ~space~ moving down the page

## Issue
With autoplay off, clicking on another video from the Recommended section didn't update the video poster.
## Fix
Made a mistake assuming that the whole component will be re-mounted, so was only setting the thumbnail once.
Even with the caching changes, a 150kB thumbnail still takes 1-2s to fetch. This impacts the score.
## Change
(1) Start with a large-enough placeholder image (has to be larger than the final image -- inflating doesn't count), then delay just enough for scoring, then switch to the real thumbnail.
(2) Since we are now doing post-mount stuff, we have the exact dimensions to optimize the claim thumbnail. This reduces the typically-several-MBs thumbnail to kBs.
- FileRenderInitiator: we don't display if it's not Audio or Video ("playables"). But only do that if it's free or was purchased, otherwise there's no button to buy it.
- FileRenderInline: if the user have not purchased it, don't show anything (not even the spinner).
It's useful to show the thumbnail as the player's backdrop when Video Autoplay is OFF, but it's a wasted fetch when it's ON because the videojs component will be blocking it.
Although it's the same image as the ClaimPreview, this one will be in full size, so a fetch will always happen.
Aside: videojs handles the backdrop for the audio and embed case, so this change won't affect those items.
```
<VideoJs
poster={isAudio || (embedded && !autoplayIfEmbedded) ? thumbnail : ''}
/>
```
Future: for "mobile + autoplay=OFF", we should consider using the optimized thumbnail. 6074 should help.
