The difference in horizontal-skylines is expected,
I believe. Accidental has some adjustments specific to
certain glyphs (flats and double flats). This is not
relevant for AccidentalCautionary because the parentheses
'hide' the outline of the glyph from the horizontal
point of view.

However, the differences in extra-spacing-width and
vertical-skylines are clearly not expected as far
as I can see. Good catch; I suggest to submit a patch.

(Homework for me: figure out why accidentals' skylines
need be unpure??)

Best,
