This is really no different from the fact that the incoming certify state
has to also be on. So a subfile won't be BFC'd unless all its parents are
certified and it is certified as well.
Also, presumably if you refer to a subfile in a section where clipping is
disabled, you do so because it won't work right otherwise. Turning clipping
back on would cause incorrect rendering.
This actually brings up the point (that may have already been brought up and
rejected when BFC was discussed years ago) that it would make sense to have
a force flag that would force certification on even when your parent is not
certified or clipping has been disabled.
That way parts wouldn't have to be treated as special cases by the renderer.
The BFC spec already says in the implementation section that the renderer
should pretend that all superfiles are certified when it processes a part.
A flag like FORCE-CERTIFY (or somesuch) would remove this special case.
