Clips in timeline cannot be moved after ctrl-alt dragging

I have just found this bug (in February 2023)...and how to reproduce it and how to fix it:

How to reproduce it (in version 23.3.0 BETA Build 35 on Windows 10)

1. Do a ctrl-alt drag of a clip to swap its place with another clip

2. That's it. If you then try to drag/move any clips in the timeline, the pointer turns to a 🚫 "no way" symbol and the clips are immovable. It's still possibe to trim, copy, paste and all manner of other things, just forget about dragging a whole clip around.

How to fix it

As someone suggested in this post, docking the timeline panel into another panel fixes it. You can then drag your timeline panel back to its original position and everything's great again.
