My safari version: Version 12.1.1 (14607.2.6.1.1)
Say I am on website A, and I use Notification.requestPermission() to allow the notification on it.
Then I quit safari, relaunch it and open website A again, I use Notification.permission to get current permission, it always return 'default', even though I can see in the Preferences->Notifications that website A has allowed notification.
Ultimate purpose: I need to know correct permission to determine if I need to show some toast for user.
