What is embed used for? Flash and videos. Both have intrinsic sizes
What is object used for? Videos, Java applets and Silverlight. They
all have intrinsic sizes.
Basically, for what concerns rendering (the element being "replaced"
in the CSS meaning of term), <img>,<embed>,<object>,<svg> have
intrinsic sizes (they may be rescaled, but this is ortogonal)

Note that I didn't include <iframe> in this list, because it could be
rendered as if the child document contents were inside the parent
document, within the <iframe> (auto height given by elements content);
or it could be rendered as a window, with intrinsic sizes given by
