[whatwg] overflow of seamless iframes

[L. David Baron]

http://www.whatwg.org/specs/web-apps/current-work/multipage/embedded0.html#seamless
doesn't seem to say what happens to overflowing content in seamless
iframes.

Overflowing content seems likely to occur with the default values of
'width' and 'height', in at least the case where content inside the
iframe that is wider than the iframe's containing block things like
floats inside the iframe 

I would suggest that the 'overflow' CSS property apply to the
handling of overflowing content inside seamless iframes.  This seems
like it would make them most like blocks.

In any case, it seems like this ought to be defined (although if it
were defined by making a more general statement of equivalence that
might be good, since I suspect a bunch of other similar things are
undefined as well).
