-- Information about the crash:
Per https://bugzilla.redhat.com/show_bug.cgi?id=2374660#c17, "I was bombarded with WebNotifications (via Firefox, from Proton Mail). When I invoked the flyout of the System Tray that contains plasmoids that aren't currently relevant, and selected Notifications, Plasma Shell hung for approximately 2 seconds, then crashed. This isn't an ANR."

The crash does not seem to be reproducible.
