In Emacs before version 31, window-inside-absolute-pixel-edges returns the wrong y-offset when the per-buffer tab-line is enabled. The tab-line is taken into account when computing the window's height, so we adjust the y-offset after computing the height. Fixed upstream in https://debbugs.gnu.org/cgi/bugreport.cgi?bug=75576. * exwm-layout.el (exwm-layout--show): Adjust the window's y-offset to include the tab-line. (Bug emacs-exwm/exwm#114)
