Still needs too, also it brings in front the window I am trying to get the tab from. But that happens to Safari too. Which is wrong cause you can't see what are you trying to move. Apple forgot that probably.
Also there's an animation on Safari when you drag an drop a tab from a window to another window.
More on the videos 🙂
