well, as long as there is no standard saying "for integral glyphs (of 
any size) you need to subtract the italic correction from the width" we 
cannot say that this is "expected behaviour"

the fact that Asana etc follow cambria in this is not making it a 
standard either; at least with tex we're able to deal with such bugs and 
i'm pretty sure that other applications also hav ebuilt ion 
compensations and fixes

if we end up in some 'we mimick the first font using some kind of otf 
technology' approach even if it concerns bugs, then what's a standard 
worth (in that respect open type is already a bit of a mess anyway)
