🐛 BUG: TSX output does not properly escape slashes in HTML comments

[totto2727]

Describe the Bug

Version

• astro: 4.0.7
• @astrojs/check: ^0.3.4

Summary

When commented out in HTML format, entering a slash immediately after a hyphen will cause astro check to output an incorrect error.
I have not been able to confirm whether this error occurs with anything other than a slash.
If you enter a instead of a slash, no error occurs.

3. pnpm astro check
4. Outputs incorrect error.

Seems to be a bug with the compiler

<!--/<div>Error!<div/>--> becomes {/**/<div>Error!<div/>*/}
