Thanks for the reminder.

This is a bug in the font. As far as I understand the idea of 'COLR'
(version 0, as we have here), the colored sub-elements, if 'summed
up', so to say, must yield *exactly* the same bounding box so that a
font engine not understanding 'COLR' can use the B/W version of the
glyph instead without any change of the layout.
The color version of glyph 396 in `p5.ttf` violates this assumption;
sub-glyph 401 is a black square around sub-glyph 400; it is not
present in glyph 396 and incorrectly makes the bbox larger than the
B/W version.
