When using fret diagrams, the "Chord/RestDuration" option for the Realize Chord Symbol tool does not work.
Steps to Reproduce:
1. Put a fret diagram on a measure.
2. Set the Chord Symbol Duration in the inspector to "Chord/Rest Duration".
3. Use the Tool > Realize Chord Symbol function on the fret diagram chord. The chord will be "realized" as if the "Until Next Chord Symbol" duration was set, which is the default duration.
