Cautionary accidental bracket has insufficient white space when applied to flats.
I have noticed that when applying a cautionary accidental to a flat, the left bracket leaves no white space between itself and the stem of the flat. Sharps are fine. Naturals are a bit close to the left bracket. This is particularly noticeable when using the Gonville font. I don't believe the are adjustments for the bracket positioning unless I apply them as stave text.
