Autoplaced chord symbol does not reset when adjustment no longer needed
Pretty sure I broke this with my most recent changes. To reproduce:
1) enter a note on staff
2) enter a chord symbol over it
3) raise pitch of note enough to trigger autoplace to raise the chord symbol
4) lwoer the note again
Result: chord symbol stays up. Got to be because I added code to not relayout "unnecessarily" in order to avoid the chord jumping up and down as you edited, clicked the rest it was attached to, etc. Somehow I need to be just a little smarter about that I guess.
Workaround is toggle autoplace off and on.
