## Issue
Closes 5811: Video-embed in markdown-post is broken
- Revert "Fix 'makeSelectIsPlaying' to look at 'playing' instead of 'primary'." dabdc980a1.
- Revert "Fix 'isPlaying' to reflect 'playing' instead of 'primary' URI" 351890decf.
Reverting means "Deleting MD from downloads list causes spinning icon to run forever 4959" gets re-opened, but this is a way less severe issue to leave in.
## Issue
Closes 3661: Autoplay + Related go into loops ( infinite ) sometimes
## GUI
Push the actual "next" item into the top of the list.
## History search
1. Skip if the next item is itself.
2. The URL stored in the history comes in various forms, so a direct comparison won't work.
- There's also a weird case where the URL differs by just a little (p.09 vs p-09), but with the same claim ID:
lbry://vacuum-tube-computer-p.09-–-building#5212bc8bc63c373e2bf1ebc5b765595ed7b6514d
lbry://vacuum-tube-computer-p-09-–-building#5212bc8bc63c373e2bf1ebc5b765595ed7b6514d
Check the claim_id as well to cover cases like these.
* initial support for block/mute
* hide blocked + muted content everywhere
* add info message for blocked/muted characteristics
* sort blocked list by most recent block first
* add 'blocked' message on channel page for channels that you have blocked
* cleanup
* delete unused files
* always pass mute/block list to claim_search on homepage
* PR cleanup
* am I done?
* post diff
* unused selector cleanup
* missed commit
* mess with button styles
* fix flow
