When clicking the "mark as read" checkmark, only the currently displayed (filtered) notifications should be marked as read.

For example, I wanted to mark only the "Space membership" notifications as read by filtering for them and clicking the checkmark. However, this action marked all notifications as read, not just the filtered ones.

Expected behavior:
Only the visible/filtered notifications should be marked as read.

Actual behavior:
All notifications are marked as read, regardless of the current filter.
