[Alan Third]

branch: emacs-27
commit 6aa9fe3e1b4052b2acde86404a90e35893ebfa00
Author: Alan Third <alan@idiocy.org>
Commit: Alan Third <alan@idiocy.org>

    Fix crash in ns_mouse_position (bug#44313)
    
    * src/nsterm.m (ns_destroy_window): Close the window before freeing
    the frame resources so we don't end up accessing the frame struct
    after it's been freed.
    
    (cherry picked from commit 18a7267c32a909bb26bd93d24543155aeb10e042)
