Steps to reproduce

Add IE conditional comments with HTML inside them.

What is Expected?

Stay hidden unless the version of IE is matched. Thus hidden in all other non-IE browsers.

What is actually happening?

IE conditional comments are removed and thus content inside the conditional is always displayed.
If there is no HTML then the content is hidden (as it should be).
