I just dismissed a reminder from #MicrosoftOutlook for #macOS. The reminder disappeared from the pop-up, but the pop-up itself remained. Neither clicking the "Dismiss" button nor clicking the red circle in the title bar made the window go away.
About 30 seconds later I went back to the pop-up and clicked on the red button, and this time the pop-up went away.
I love software that behaves non-deterministically! How about you?
