- Add close button to allow immediate dismissal.
- Add ability to support sub messages. Will be typically used for error codes, etc.
- Add ability to define 'long' auto-dismiss duration (15s) vs. the default of 5s.
- I didn't add 'off' because there is a comment saying that this scenario should use the Error Modal instead, so respecting that for now.
* Fix avatar occasionally stuck in spaceman
## Issue
Sometimes, we'll see a channel profile (e.g. in upper-right, in channel selector) stuck in the fallback Spaceman image.
This is due to OptimizedImage always starting with a blank src, and updated later when the mounted size has been determined. ChannelThumbnail, which uses OptimizedImage, captured the `onError` due to blank src.
## Fix
Don't mount the <img> until the optimum size has been determined.
* FileThumbnail: skip resolve if thumbnail url is specified
* UriIndicator: skip resolve if channel info is specified
* Notifications: disable batch resolve + use fetched data if available + fallback to resolve if n/a
The fallback is using the individual resolve when no direct data is provided and claim is undefined.
