You're right, the chords are transposed correctly.

But there's still a different behaviour between {comment:  and {comment_italic: 
Within {comment_italic: the chords are displayed formatted as chords, within {comment: the chords are formatted as comment.

The behaviour has changed a while ago, I can't say when.

I used the .pro file from my first post to make the attached screenshots.
