Documents not rendered if they start with HTML comment

[EuropeanDeveloper]

Documents are not rendered if they start with HTML comment.

Example:

<!-- HTML comment -->

# Lorem Ipsum

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor
incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis
nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Result:

Version: Markdown Viewer 5.1
Browser: Mozilla Firefox 111.0

I'm not able to reproduce it on my end. I tried with both compilers and using different option combinations. Not sure what else can be different.

I used the default settings. Still, the HTML_Comment_Test.md file is not rendered.

It works both on file:/// and http://localhost on my end, MV 5.1 and FF 111 on Linux.

[EuropeanDeveloper]

I've tried it on Windows 11, maybe is it because of that?

That's even more strange, the web rendering part of Firefox should behave the same on all platforms.
