Figma embed block on p2 doesn't work with figma prototypes

[jeffgolenski]

Steps to reproduce

1. Starting at URL: WordPress.com - navigate to a p2
2. Embed a prototype directly, such as this one
3. Inside the block editor, the prototype will load properly.
4. However, when you preview the post it doesn't load the proper screen. It load the cover image, not the prototype

What I expected

For the prototype to load in the preview, as it does in the block editor as I'm writing the post

What happened instead

Prototype does not load

Browser / OS version

Context / Source

I'm unsure if this is the proper place to record this bug. Is it a wordpress.com editor issue? "p2enberg" or figma? Unsure.
