## Issue
3779 RSS feed for channels
## Initial implementation details
- RSS only (not atom)
- Grabs latest 10 entries (Beamer have concerns)
## Credit
Referenced the community version mentioned in 3779
- The `rateChange` event now logs the updated speed,
not just the time at which it occurred.
- The `scrub` now (more) accurately logs the position
it came from before the destination.
- The recsys events get consolidated for logical consistency.
## Issue
With autoplay off, clicking on another video from the Recommended section didn't update the video poster.
## Fix
Made a mistake assuming that the whole component will be re-mounted, so was only setting the thumbnail once.
Even with the caching changes, a 150kB thumbnail still takes 1-2s to fetch. This impacts the score.
## Change
(1) Start with a large-enough placeholder image (has to be larger than the final image -- inflating doesn't count), then delay just enough for scoring, then switch to the real thumbnail.
(2) Since we are now doing post-mount stuff, we have the exact dimensions to optimize the claim thumbnail. This reduces the typically-several-MBs thumbnail to kBs.
These are chunks that will be requested immediately after ui.js when opening the homepage, so consolidate them into 1 chunk to reduce network overhead.
More work can/should be done to reduce the secondary chunk.
Make immediate GUI feedback to convey the current status, which can be the following:
- typing
- waiting lighthouse results
- waiting claim resolve
- no results or failed.
## Issue
6301: don't use CDN for GIF thumbnails
## Note
Just a minor mistake in the recent thumbnail refactoring; left out the handling when `allowGif` is true.
