Active Drum input palette won't close if more than one file open
2.0.3 / Win 7/10
1. Open any file in Musescore. Then open the attached file.
2. Enter (percussion) note input mode by pressing "N".
3. Close the file. Leave the other one open.
Expected result: The program should automatically exit note input mode when the file closes. The Drum input palette should also close.
Actual result: The Drum Input palette is still open after the file is closed. You have to close all open files to close the palette.
