## Issue
- Large resolve count (albeit batched) on bootup.
## Changes
- Skip the call on bootup. The same call will happen when you click the notification bell, so it's not too late to resolve at that time.
- Added `true` to `doResolveUris` to return cached results, otherwise it will keep resolving the same channels every time we enter Notifications Page.
Initially, the filtered list was done at the component level, and the list was simply a subset of `notifications`. But due to the limit issue explained in 5694, we now query the filtered list instead.
Considerations:
- The filtered list could contain items not listed in the 'All' list. We could add a string at the bottom of 'All' that says "not all items retrieved" if this confuses the user.
- The unseen count needs to be based on 'All' and not the filtered one, so that data needs to be stashed somehow (can't re-use the array).
Use 2 arrays for now instead of trying to accumulate "all" and "filtered" into 1 array.
## Issue:
Closes 5515: All videos marked as read when clicking a single notification from notification list
## Change:
- Augment `doReadNotifications` to only clear the given IDs. If the argument is `null` or is not a valid array (e.g. when used as a click handlers, the click event object is passed in), all notifications will be cleared.
- Augment `NOTIFICATION_READ_COMPLETED` to only clear the given IDs.
## Notes:
- Wasn't sure of the API will fail if the ID is invalid, so I start from `unreadNotifications` first, then only filtering it further with the given ID. Otherwise, we could just skip the `unreadNotifications` filtering.
