Can you embed HTML in the Preference Center?

A few months ago my firm successfully embedded HTML into the welcome message field on customization screen for the Preference Center creation page. (We added H2s and strong tags here and there).

Now that I've returned to update the welcome message a few months later, the HTML embedded in the text editor isn't being read as HTML. All the tags are being outputted as plain text when I preview what the preference center will look like.

Is there a trick to getting the HTML to render or is HTML no longer supported in this area? Any advice? Thanks for the help.
