I’m not sure. Isn’t that a reply notification in my video? And yet, there is still a notification about the quote and the link afterward. So, extending that for other notification types might not help here. But maybe it covers other edge cases.
I wonder if the problem in my repro is the “2 replies” notification. Does that break the check for existing notifications by that reply when the reply is edited?
In general, I would expect no additional notification because of an edit if all the triggers had already been in the post when I read it before. Fixing a typo unrelated to mention/link/quote shouldn’t result in a new notification.
I think, in case a trigger is replaced, I would rather like the existing, unread notification to be changed (or replaced) than receiving a second one. Removing the @mention in a user’s post to avoid noise shouldn’t result in a second notification about the quote. I would expect the notification about the @mention to disappear.
I think the only case where I’d want a new notification is if an edit adds a more important notification type. So when someone linked my post and later adds an edit which @mentions me, it makes sense to tell me because they seem to be talking no longer about something I wrote but directly to me. Since an edit no longer bumps the topic, @mentions might be a helpful way to alert users about edits.
