## Issue
In the Channel Page, if the _Collections_ `claim_search` comes in after the main content's `claim_search`, the Collection's `ChannelContent` is being re-rendered despite not being in the active Tab. This causes a 0.4 CLS score (it's ridiculous that invisible components are taken into account). Apparently 41% of users are hitting this scenario, causing a poor aggregate.
## Change
Don't mount the `ChannelContent` components unless its tab is the active one. It doesn't seem like Reach Tab hides components under the inactive tab.
No functional change; just thought this is cleaner (group up the constants) and easier to type via IDE auto-complete, at the expense of creating an extra object.
## Issue
Creating Settings suddenly start to stop loading correctly for some of my channels.
## Change
`settings.List` now returns null instead of empty array. Double-checked the Commentron repo and this is indeed the case.
Updated the code to handle null.

6068 Fix "Cumulative Layout Shift" for Core Web Vitals
In Posts, the Comments section appears first while we fetch the MD file. When the MD is fetched, Comments get pushed to the bottom (or shifted up for short posts), hence the red CLS scores.
## Approach
There are too many layers between `<FilePage>` and `<DocumentViewer>` to pass the `loading` state around to hide the Comments section, so just make Comments fade in after a 2s delay.
## Changes
- Posts: Add 2s fade-in delay to Comments.
- Posts: remove the gray placeholder. This improves the score a bit more, and reduces flicker as well. There's already a spinner from `FileRenderInline` to tell the user to be patient.
- Posts: add a minimum 30vh height so that short posts don't get collapsed too much, causing the `FileDetails` and Comments to shift. Small shifts are fine as long as CLS is below 0.1.

6542 Livestream listing and blocked list kills CLS score
This is basically a repeat of what was done on `claimTileDiscover` (homepage), but now on `claimListDiscover` (category pages).
This handles the unnecessary re-render when:
- the uri list temporarily being zero while waiting for new claim-search results.
- livestream claim-search invalidating the list.
## Changes
Store the last uri list and use that when we know that claim-search is still not done.
## Tests
1. Ran Lighthouse on category pages (force a livestream channel on it). CLS score must be green.
2. Block `claim_search` from Dev Tools and move to another category. The page should say "timed out" instead of "no results" (i.e. maintain existing behavior).
## Issue
6589
## Notes
`parseURI` will return `isChannel=false` due to the reposted channel URL not having the '@' symbol.
Since we already have the claim object, check `value_type` directly instead.

Recently changed to `<OptimizedImg>`, which was assuming the `src` never changes.
dejavu ... we also hit this issue when implementing the `IntersectionObserver` lazy-loading.
Objective:
- Get appropriately sized images to improve performance and Core Vitals score.
- Ensure images using "objectFit=cover" doesn't get stretched out if the source is large enough.
- Peg to 100px increments for better caching.
Notes:
- Skip images hosted in '/public'. If we really want to optimize it, then we'll need to provide the full path in the code, otherwise CDN lookup will fail.
If there are no API errors but no reactions returned, consider the requested IDs as "done" and stop requesting again. When a channel is being confirmed, Commentron doesn't return the reaction object.
Also added extra guard in case Commentron does return an object in the future, but an empty one.
- use `selectActiveChannelClaim` as that takes the current channel list into account (i.e. correct state when all channels are deleted).
- `selectActiveChannelId` should probably be removed or not exposed through a selector, as it is not updated when channel list changes?

## Change
Lock all images to fit a 16:9 container. We have implemented 'ZoomableImg', so no reason in trying to display in full size.
This reduces CLS from 0.4xx to 0.01x.
## Flaws
CLS could probably be zero if not for the spinner shifting things slightly. Also, mobile CLS is 0.07.
The troublesome part in this PR is that FileRenderInitiator, FileRender and their subcomponents are broken apart and it's hard to synchronize their visibility and size. There are time gaps where none of them are visible, etc.
This PR only tackles the major part (most bang for buck), which is the elimination of variable height of the rendered image.
## Aside
I think `claimIsMine` is unused, so don't waste time requesting it.
