Konsole Monitor for Silence Notifications Not Working?

I’m trying to get Monitor for Silence notifications to work in Konsole, but they aren’t coming through when silence is triggered. I have Monitor for Silence set in View for a pane, and I double-checked that my notification settings are configured to send a message when monitoring. But, when the pane hits the silence threshold after 10 seconds, I get no notifications. I’m confident it’s catching silence because the “sleep” icon pops up on the pane.

I tested further by running dbus-monitor "interface='org.freedesktop.Notifications'" in a separate pane to watch the notification interface, and testing with a notify-send call to ensure I could see notifications coming through. With that running, once the terminal that I’m monitoring goes “silent”, I don’t see anything come through the dbus monitor. It’s almost like Konsole isn’t even trying to send the notification for it.

Is there something I’m missing here? I’ve triple and quadruple checked my notification settings, both in Konsole and in System Settings, and it should be sending system level notifications. But I don’t see it even try.
