New Forms Modal Message Adding HTML?

I am redoing our forms thus, I am moving over to the new forms. I have a pop-up message on my legacy form that utilizes some HTML. It's a safeguard to stop our end-users from just clicking okay without reading the message (which they were doing originally when it was just plain text). 

With the new forms, I tried doing the same in my new Form Rule but it just shows it as plain text. Is there a way to achieve this with the new forms? Or is this no longer a feature?

Example of what we want:
<Center>
<img height = 100px src="image_link">
<p style="color:red; font-size:25px;">SKIPPED Steps</p>
<p>Please review the <span style="color:red;">Skipped Step</span><strong>BEFORE</strong> starting the Payroll Process.</p>
