Thanks for the bug report, and the screen recording, which shows exactly how to reproduce this bug. I'm able to reproduce this in Neon User Edition, following the steps in the video. I am *not* able to reproduce it with git-master with those same steps. This will be released in Plasma 6.4.0. This bug should be fixed on your system when your distro has updated Plasma to 6.4.0. If the bug is still present on your system with that or a later version, please feel free to reopen this bug report. Thanks!
Cool!
