OK, I looked into this a bit further and it seems this stuff is in the
accessibility API. I’ve attached a couple of patches, please apply
‘fix redefinition of child frames on NS’, then ‘Set accessibility
subroles for child frame’ and see if it does what you expect.

This will only work on macOS >= 10.10. I think there must be another
way of doing it on older versions but I haven’t found it yet. I’ll see
if this works before digging any more.
