Looks like an acquisition bug:
obj.aq_inContextOf(context, 1) is recursively defined by:
True, if "obj.aq_base == context.aq_base"
or "container(obj) is not None"
and "container(obj).aq_inContextOf(context, 1)"
where "container(obj)" is "aq_parent(aq_inner(obj))"
which is the container containing "obj".
which is equivalent to (resolving the recursing):
obj.aq_inContextOf(context, 1)
iff for some (hierarchie) ancestor "a" of obj,
"a.aq_base == context.aq_base".
Given this definition, you can check which implementation
is wrong and file a bug report.
