Application: plasmashell (6.4.3)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.1
Frameworks Version: 6.16.0
Operating System: Linux 6.15.8-200.fc42.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 42 (KDE Plasma Desktop Edition)"

-- 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.
