Play chord symbol previews more judiciously

Your idea

Every time you click on a chord symbol, it is played back. Make sure Preferences > Note input > 'Play notes when editing' and 'Play chord symbol when editing'* are on.

There are a couple issues with this:

• When you double-click a chord symbol to edit it, it is played twice
  • It should only be played on the first click, not the second
• When you're in edit mode and you click within the field to move the cursor, it is played
  • It shouldn't be played every time you click inside. However, it should still be played when exiting edit mode (or when moving to the next chord via space/semicolon/etc.)

*The copy for these preferences will be updated in this PR

Reproduce the double-click and in-field cursor-click cases with both note-input preferences enabled. Trace the chord-symbol editing and playback behavior, then verify that the symbol plays on the initial click and when editing ends or navigation moves to the next chord, but not on the second click or cursor repositioning.
