Launch Nightly 2. Resize the window 3. Maximize the window 4. Fullscreen the window and exit from full screen. [Expected result]: The tab will return to the tabbar without any problems [Actual result]: The tab jumps when exiting from fullscreen
Thanks for reporting! I'm able to reproduce this. I noticed that if we didn't call TabsInTitlebar.updateAppearance(true) in FullScreen.toggle(), the tabs would remain in their incorrect position after exiting fullscreen. We seem to fail to restore window.STATE_MAXIMIZED properly when exiting fullscreen.
