:gstoll, since you are the author of the regressor, bug 1915351, could you take a look? Also, could you set the severity field?

The notifications continuing to display is just how Windows behaves - Firefox creates all those notifications at once and Windows displays them one at a time after a delay.

But bug 1928064 covers showing multiple notifications for the same user action, so after that is fixed we should just show one notification. I'll dupe this to that.
