An example of this would be the FFmpeg custom options dialog. When the options dialog would close, focus would be lost and with no apparent way to get it back when using the keyboard. This change tracks the modal dialogs that are opened after the current file dialog and that are descendants of the current file dialog. Once all of the descendants are closed, the current file dialog will restore the focus and make sure it is the topmost window. This only affected Windows.
