My best guess is they tweaked something in the font and anyway this is NOT Emoji rendering.
ie those letters in dashed boxes are just mapping to the ordinary glyph rendering.
As such it doesn't go down the path I added for getting full bounds of Emoji and all it really
means is that it is a separate bug for ordinary glyph bounds/metrics. ie if you separated those
it would make no difference - they'd still be clipped.
