Now change "pizza" to "urn:pizza" (or anything that doesn't resolve in
DNS) and add something inside the <object>.

See also some of the tests here:

Basically <object> is so incredibly unreliable in IE that it is unusable.

It doesn't discard them, it keeps enough information in the DOM to
reconstruct unknown elements. (To be precise, it converts unknown start
tags to empty elements and unknown end tags to empty elements with the tag
name prefixed by a slash.)
