Embed HTML Markup in Form Title

I’d like to style a few characters of my title differently from the rest using a span tag. When I do this, CCF display the markup literally, instead of letting the browser interpret it.

Example of what’s literally being rendered:

Contact Us!<span id=”SM”>SM</span>

Is there a way to make this work?
