`deno fmt` does not terminate with 10 MB HTML file

[nicolo-ribaudo]

Version: Deno 2.5.4

I'm trying to parse a large HTML file, which contains "invalid" HTML (it has some self-closing tags that cannot actually be self-closing, which causes it to have also unclosed tags and not properly nested tags, as well as a <?xml ... annotation in the middle of the file).

Browsers render the file in a normal time, and https://github.com/jhy/jsoup can parse+print it in about 2 seconds (but it has some bug that makes it parse the file the wrong way). Prettier takes 25 seconds.

I left deno fmt running for 15 minutes and it gave no results.
