Editor stays blurred when moving panels

[nexes]

Issue Type: Bug

When moving the different panels around, Problems, Terminal etc, the editor will have a blurred effect. This effect doesn't go away if I move a panel but put it back in the same place. Here is a GIF of the problem.

I had this issue as well, seems like the "Multiple views in a single panel" feature doesn't work if the 3-dot-menu is shown, like below:

If the 3-dot-menu is shown, it will glitch and the editor will have that "blurred effect". To remedy this for now, I either:

1. Zoom out (Ctrl + - on Windows, probably CMD + - on Mac)
2. Resize the window

until the 3-dot-menu disappears, and then the feature should work.

Thanks for reporting @nexes and the explanation @miXwui

With the repro I discover that this happens when the number of panel tabs shrinks during the drag operation which seems to happen frequently when dragging Problems and Terminal.

If you hit the sticky blur, for now, you can drag the active tab and drop it immediately. This should get you out of the bad state.
