If you analyze the finer detail of the CSS spec, CSS capable and enabled
browsers should determine the size of embedded HTML, despite the fact
that it has no /intrinsic/ size. However no browser that I know of does
that. Without a specified width and height a browser may collapse width
and height of the viewport established by the object element to 0 (IE),
or default to a certain non zero value (Opera, Gecko).

Ergo when embedding HTML you should always specify a width and height
for the viewport established by the object element via the width and
height attributes on the object element. Since you can only specify a
size in pixels that way, you could elect to also specify a width and/or
height with CSS, in which case you have other units available.
