Affected packages and versions

MDX v1.8.9

Link to runnable example

No response

Steps to reproduce

Open VSCode (v1.92.0), with MDX extension (v1.8.9), and the syntax highlighting on MDX files is broken.

This was working yesterday and appears to have suddenly become broken when I updated VSCode to the latest version.

Syntax highlighting works fine up until the closing 3 dashes --- at the end of the frontmatter, and from then on out it's broken:

Note how the top --- is correctly orange, but the bottom --- is not.

All text after this appears red when it was previously white:

I have done the typical extension uninstall/reinstall, also restarted my machine and VSCode since encountering this issue, so it's not that.

Expected behavior

The syntax highlighting works.

Actual behavior

The syntax highlighting doesn't work.

Hi! Thanks for taking the time to contribute!

Because we treat issues as our backlog, we close duplicates to focus our work and not have to touch the same chunk of code for the same reason multiple times. This is also why we may mark something as duplicate that isn’t an exact duplicate but is closely related.

Thanks,
