Chord symbol "warning color" issues and lack of automatic reversion
Red "warned" chord symbols export in both print screenshot mode and PDF as red.
Chord symbols which have turned red to warn of possible unintended input do not return to black when the character(s) that triggered their redness are removed.
The logic governing the chord symbols' "warning redness" is incomplete and still allows a whole lot of possible chordal non-sequiturs.
