Created attachment 95573 [details] Screenshot of "leftover" popup after the panel already disappeared The panel auto-hide animation currently doesn't wait for any popups to be closed first. This leaves the popup in the middle of the screen and the hiding animation of popups and the panel itself runs in parallel then after another, so popups will disappear into nothing/the middle of the screen (see attachment). Instead, when the focus on an auto-hide panel is lost, the panel should only disappear once all popups have finished their hiding animation.
