No response

Describe the Bug

I didn't try to use JSX in Astro frontmatter, but still encounter this.

39 |  article[lang|="en"] {
40 |    font-family: "Noto Sans", sans-serif;
41 |  }

The stack trace shows it's at 39:571, which doesn't exist.

What's the expected result?

It should build without error.
