Undocked items can't be dropped on secondary monitor.

When undocking an "item" the drop location has to be on the same screen / monitor as the main stage. It is also not possible to move an undocked item to another screen.

This works perfectly fine for me, what is your setup?

I checked again today and it works fine. No idea what was going on then.
