Undocking time line window results in a freeze for the time line

[maxthi]

Describe the bug
When I open hotspot and press on the "Undock window" button of the timeline window, the timeline window undocks as expected, but is completely unresponsive. I can neither click on anything nor move the window around. It can only be fixed by going to View->Restore Default Layout. I am using hotspot in WSL.
