## Issue
Fixes 4293 `Better download link support`
- [x] make it so you can right click a download button > copy download URL
Given that this could be useful in mobile/web as well, I used a button+modal instead of the right-click approach.
- [ ] in share dialog, show download URL to copy for non-video content
This is already implemented, albeit hidden in the "More..." expansion.
## Issue
Fixes 4460 `unmuted state lost / reverted`
1. Play a video.
2. Press mute.
3. Drag the volume bar to unmute.
4. Play a new video --> the video starts muted.
## Fix
The `volumechange` handler was comparing against stale variables, so there are times where the state was not saved. Just save both `muted` and `volume` without additional gating (the gating is probably unnecessary in the first place, since we are in a onChange function).
## Fixes:
3641 Language switch does not take effect right away
## Assessment:
Although `Card`s in the Settings Page are actually being re-rendered, the `actions` within them might not be getting the signal, depending on their props.
## Changes:
(1) Pass the language variable to the `actions`'s props for items that are affected.
(2) Make the Wunderbar listen to language-changes as well (the only component outside of Settings that would need an immediate update).
1. Use a constant for the classname instead of being hardcoded.
2. Use existing 'debounce' function instead of introducing another.
3. Added changelog entry.
---Fixes:
#-2882: "Fix UX around publishing to already published URL".
---Changes:
1. Improved the error message (change color to red; emphasized the URL; tweaked the sentences a bit).
2. The `Publish` button will be grayed out in this scenario, until user explicitly decides to edit existing claim instead.
