- [x] (6332) The IntersectionObserver method of lazy-loading loads cached images visibly late on slower devices. Previously, it was also showing the "broken image" icon briefly, which we mended by placing a dummy transparent image as the initial src.
- Reverted that ugly transparent image fix.
- Use the browser's built-in `loading="lazy"` instead. Sorry, Safari.
- [x] Size-optimization did not take "device pixel ratio" into account.
- When resizing an image through the CDN, we can't just take the dimensions of the tag in pixels directly -- we need to take zooming into account, otherwise the image ends up blurry.
- Previously, we quickly disabled optimization for the channel avatar in the Channel Page because of this. Now that we know the root-cause, the change was reverted and we now go through the CDN with appropriate sizes. This also improves our Web Vital scores.
- [x] Size-optimization wasn't really implemented for all ChannelThumbnail instances.
- The CDN-optimized size was hardcoded to the largest instance, so small images like sidebar thumbnails are still loading images that are unnecessarily larger.
- There's a little-bit of hardcoding of values from CSS here, but I think it's a ok compromise (not something we change often). It also doesn't need to be exact -- the "device pixel ratio" calculate will ensure it's slightly larger than what we need.
- [x] Set `width` and `height` of `<img>` to improve CLS.
- Addresses Ligthhouse complaints, although technically the shifting was addressed at the `ClaimPreviewTile` level (sub-container dimensions are well defined).
- Notes: the values don't need to be the final CSS-adjusted sizes. It just needs to be in the right aspect ratio to help the browser pre-allocate space to avoid shifts.
- [x] Add option to disable lazy-load Channel Thumbnails
- The guidelines mentioned that items that are already in the viewport should not enable `loading="lazy"`.
- We have a few areas where it doesn't make sense to lazy-load (e.g. thumbnail in Header, channel selector dropdown, publish preview, etc.).
* Release date -- initial attempt (squashed and rebased)
- Use white color for calendar buttons in release date input
- Update icon color for release date input
- Allow to set time in release date and display it under additional options
- Add release date field
* Upgrade to latest react-datetime-picker.
I believe this also picks up the y18n security fix.
* Handle dark theme and general style fixes.
* [+redux] Change how release_time is edited.
- `releaseTime` is now a number instead of a string, matching `release_time`. It was getting confusing what the variable units were.
- `releaseTime` will always match `release_time` for an edit. It will be used in the GUI to reset just the date to the original, instead of having to reset the entire form.
- `releaseTimeEdited` will be used by `updatePublishForm` in the GUI to represent the desired new release time. Set to `undefined` if we don't want to change the date.
* Add 'Reset|Now|Default' buttons instead of overloading the date-picker's "X" button.
Before this, the "X" button resets to the original (previous) publish date for Edits, and resets to current time for New Claims. This is very confusing, so added explicit text-based buttons -- hopefully this is more intuitive.
* bump redux to master

## Issue
Closes 5721: Publish-Preview updates
## Changes
(1) Match the recent "incognito" change that sets the channel to `undefined` via `updatePublishForm`. This change would also cover `null` -- I don't think it's being used to represent something else, so showing "Anonymous" for `null` should be fine.
(2) Added channel icons, so it'll be more obvious to the user if they accidentally selected the wrong channel.
- Channel About
- description: seems handy to have a preview, so pulled in the "allowed" logic.
- email: shouldn't render preview at all
- website: shouldn't render preview at all
- Publish Preview:
- description: there's not enough height anyway, so don't render preview.
This option allows users to bypass the "publish preview" modal. Users can disable it by checking "don't show this again" in the modal, and re-enable it in the Settings Page.
