The only downside to this new implementation is that the top-most (or right-most?) scrollbar won't get the customization. Any other sub-components (e.g. sidebar) will get the customization.
My guess is that the "top-most" scrollbar is above the `main-wrapper`. I'm not sure if we can (or should) add another className higher than App.
The impetus for the customization was the ugly sidebar anyway, so at least we covered that.
## Issue
4727: Sidebar's transient scrollbar doesn't fit in the Dark Theme
## Approach
The 'webkit' API works on Chrome, but Firefox ignores it and uses it's own fancy scrollbar when 'webkit' is used (can't seem to change any properties). It's better than the current look, but still doesn't fit our theme, plus it makes the product look different on different browsers.
Firefox now supports the new 'scrollbar' API, so we can now tweak the scrollbar, but the API only provides limited attributes.
Don't wanna complicate things by using Javascript, so we'll use Firefox's limited attributes as the common denominator and just live with a plain, rectangle scroll bar BUT with better color to match the theme.
## Issue:
5044: Auto hide cursor on video on static hover
## Approach
The existing code only hides the cursor when playing in fullscreen. Extend that to normal mode as well.
## Extra
Add in few new strings
- Fix my previous mistake of removing a string. The new "Tailor your experience" had a diff that looked like a replacement, but it was actually a new file that was probably cloned from the settings file.
- Add few more new strings.
4913: Can't slide volume slider in pop out mode
I first tried to handle this at the floating player level, but it was impossible to hack there due to how 'react-draggable' works (it already moved the window before the "move" handler is called, so we can't do much).
Fix by overriding the dragging behavior of the videojs' VolumeBar class by not propagating the event further. It is odd that videojs didn't already do this, since it's SeekBar does stop the propagation.
## Issue
4609: If claim search on latter page fails, don't clear out all previous data
## Note
This requires an accompanying change in `lbry-redux` to mark `claimSearchResultLastPageReached` during timeout and to not purge past results.
## Change
The previous flow was: increment the page, and expect the next render to either be 0 (timeout + purge) or fill in at least 1 new item.
Since it is now possible for no results to be returned for the new page (due to timeout + no purging), the code continues to make another query. This commit stops the perpetual querying.
## Test Case:
1. https://lbry.tv/$/discover?t=imherelbry&content=video&order=top&fresh=year
2. Scroll down a few pages until it timeout happens. Past results are gone.
## Issue
In the odysee branch, the tooltip for "Following" in the Sidebar was shown as "Following --[sidebar]--". In lbry.tv, the tooltip doesn't appear.
I believe the tooltip appeared due to the name change from 'label' to 'title' and then being passed to Button through '...passedProps'.
Fix by explicitly setting the Button's 'title' to the localized text.
