Wider post area for bigger text, while keeping the character count the same or less.
Removed `overflow: auto;` as it was not required and was creating unnecessary scrollbars when margins were incorrectly calculated.
## Issue
- Personally annoyed of having to switch to landscape just to change the setting. There's still space for it.
- This serves as a quick fix until "4712: Video: Allow access to all control in small screen" is figured out
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
