Hello. Steps to reproduce: 1. Take 1 desktop preview and drag it to right free desktop(autoexpanding should be enabled). 2. Drag to last desktop again. 3. Now list isn't updated and you need to switch to desktop with opened windows and then new desktop appears. Proof video below.

I'm quite confused by the video. Why is there additional desktops appearing? Do you have System Settings open in parallel and are adding new desktops?

Go to System Settings -> Window Management -> KWin Scripts and download/enable Dynamic Virtual Desktops script
It would have been helpful to mention there's some strange addon script being used ...
I don't fully understand this bug yet, but it seems to me that... The issue you're trying to demostrate is last part of your video where you drag a window a new desktop is not created/shown untill you hit the last desktop one more time right?

Yes.
That's a bug in the third-party add-on script you're using, please report to the script author.
