fix: handle closing tags in attributes

...when detecting script language
Related to sveltejs/language-tools#2204
Let me know if there's any other place where this needs a fix

LGTM.

If we backport this to main, we also need to update these two places (for error reporting only):

vite-plugin-svelte/packages/vite-plugin-svelte/src/utils/error.js

Line 118 in cf1ef58

const scriptRe = /<script(\s[^]*?)?(?:>([^]*?)<\/script>|\/>)/gi;

vite-plugin-svelte/packages/vite-plugin-svelte/src/utils/error.js

Line 145 in cf1ef58

const styleRe = /<style(\s[^]*?)?(?:>([^]*?)<\/style>|\/>)/gi;

Thanks! I'll do a corresponding PR for main 👍

can we do it on main first and cherry pick the change to v2? now that main is no longer in pre-release that flow makes the most sense to me. although with the amount of changes between main and v2 it can become difficult to pick sometimes.
