To reproduce:
- Go to Preferences > Websites > Notifications.
- Add a site, eg., Discord and choose Allow.
It will then save it as 'Ask' instead of Allow.
Only works when you edit it after adding a site.
It happens regardless of what the default setting is for all websites.
A clean profile did not fix it.
Choosing Allow should say Allow.
