dialog opened from menu on macOS does not restore active state of parent window when closed

• Start attached project
• Click the tool button Open [From Button]
• Click Cancel

Note, the focus has returned to the window.

• Switch to the Finder and switch back to the application - OK
• Click the menu arrow and select Open [From Menu] 
• Click Cancel

Note, the focus has not returned to the window, it is inactive. Touch Bar still has Cancel and Open buttons like it was while the dialog was shown (Touch Bar Shot.png).

• Switch to the Finder (or any other app) and switch back to the application - empty QFileDialog appears (QFileDialog.png). All controls in this dialog are inactive, Esc button doesn't hide it. The only way to hide it is to press Cancel on Touch Bar.

Note, if you activate the application window before switching to the Finder - the file dialog will not appear, Open and Cancel disappear from the Touch Bar.
