@domesticmouse would you be willing to take a look at this? you were a reviewer on the PR. it's blocking proper formatting for the LLM messages of the Flutter AI Toolkit, which uses a MarkdownBody to show rich text output. Thanks!

My commitment to this package is to make sure changes have test coverage. I don't actually know the code base. @gspencergoog may have thoughts on how to fix this.

Thanks to both of you. The bug in question has a suggested fix.

I've put together flutter/packages#7927 with this fix applied, but the current tests don't pass. Can you debug? And add required tests for your use case?

Thanks, @domesticmouse. I'll take a look ASAP.
