@MaxwellGarceau its hard to tell with the GIF attached, but I assume the "shortcode test" text transforms into a paragraph block while the Mailchimp shortcode transforms into the Mailchimp block?

[MaxwellGarceau]

That's correct @jeffpaul. I've attached a better screen capture and I'm updating the PR with the screen capture that shows the paragraph text to paragraph block transformation more clearly.
