Notification icons not being updated on macOS 26.4 #34
Description
Notifier sets the Alert and Banner apps icons via: https://developer.apple.com/documentation/appkit/nsworkspace/seticon(_:forfile:options:)
After which, it restarts NotificationCenter to register the new icon.. nothing fancy.
The above has worked from macOS 10.15 up until macOS 26.4.. the icons are updated in Finder.. but the Notifications show the original app icon.
macOS 26.4:
macOS 26.0 (have tested macOS 12.0 and macOS 26.3.2 too, same result): 
If you reset the notification entry in System Settings.. the approve/allow prompt has the new icon set via setIcon.. but the entry in System Settings has the original app icon, as do all posted notifications.
