Quit dialog doesn't return focus to frontmost window

[vaska0@…]

When I attempt to quit but think better of it when the "really quit?" dialog is displayed (i.e., select cancel), the window that had been frontmost is no longer active. Other X11.app windows also seem to cause this (not applications, but the X11.app preferences window and the Applications menu Customize window).
