Re: ISSUE-230: OBJECTS_AND_SCRIPTS needs to address <object> with multiple children [mobileOK Basic tests]

I don't mind taking that view, but, it seems that when the body of an
<object> tag, which is the fallback that is rendered when the <object>
can't be, is at least partially not supported, this should not be
considered OK any more than if the body of the <object> was a single
other <object> that can't be rendered.
