Since I upgraded to macOS 26 I noticed an annoying issue. When closing Thunderbird window and going back to another application the focus is being kept by Thunderbird for a few second making it impossible to click on the other app. Steps to reproduce: * open Thunderbird * close Thunderbird window (using Cmd+Q or clicking the red button on the top left corner) * click on any element of the Desktop Expected: * the element is selected Result: * nothing happen After a few seconds (from 1 to 3), the macOS menu change from Thunderbird to Finder and then everything works properly. Any help would be much appreciated.
