Toolbar note duration after undo

1. Create new score
2. Press "N" to begin Note Entry mode
3. From the Note Entry Toolbar select a duration (such as half note)
4. Add a couple notes to the score
5. From the Note Entry Toolbar select a different duration (such as quarter note)
6. File > Undo
7. Add another note to the score

Expected behavior: The note added to the score in step 7 above should match the duration indicated in the toolbar

Actual behavior: The note added to the score in step 7 is a half note but the Note Entry toolbar says it should be a quarter note.
