5090: When sorting channels, switching between Trending/Top/New returns viewer to the top of the page
## Approach
- Add an optional parameter to `ClaimListDiscover/Header` to add an additional anchor ID when building a new search URL.
- Clients then add the anchor ID on the desired location.
- The code that handles the scrolling then checks if the `location` contains an anchor hash. If it does, we'll scroll to that element; else, the existing behavior will be used.
## Issues
(1) 4783: New search query does not reset to the top
(2) The current way that Tag Search resets the position can be overridden by the AppRouter's call.
## Approach
Listen to `search` changes as well. This basically covers any search param changes.
Components should probably not call `window.scrollTo` directly as the AppRouter's call might override it.
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.
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.
I believe we don't translate these since this is already the translated form?
When the language is supported later, the English version will be added to the string database instead.
## Issue
4393: Tag query URL goes on indefinitely as you change between [Trending|New|Top]
## Change
Change from `append` to `set` when building the query to remove duplicates.
Flow hates null being not a string, so the FixMe was retained.
