Certain markdown files that start with HTML fail to render with the Firefox extension, while Chrome renders them correctly.

Broken Rendering in Firefox:

guetzli.md
typst.md
upgit.md
creold.md

All you have to do to break the rendering is include HTML before any markdown.

Insert this at the top of any .md file and it won't render in Firefox:

<p align="left"><img src="https://www.whatever.com/image.jpg" alt="Alt text" width="128"></p>

Chrome handles it fine.

Would love a bug-fix!
