Moving tabs from one window to another does not work

[aperum]

I really love this customization! The only thing i'm missing is moving tabs between windows. Usually one can drag and drop a tab onto the tabbar of another firefox window to move it there. With this customization that doesn't work anymore.

Hope this clearifies things a bit. This is on Windows 10 btw. Looking at both versions now i can see, that the colorbar for the container on top of the tab is also missing with penguinFox. But i can open another issue for that if necessary.
