Describe the Bug

Summary

parser does not handle HTML optional end tags such as <p>one<p>two.
It requires an explicit closing tag for not void elements such as p, ul, select, table

• <p>one<p>two
• <ul><li>one<li>two</ul>
• <select><option>A<option>B</select>
• <table><tr><td>A<td>B<tr><td>C</table>

Repro

<p>one
<p>two

Expected

It should infer the first </p> before the second <p> or produce AST to two sibling paragraphs.

<p>one</p>
<p>two</p>

That's the new compiler, and that's the expected behaviour. It's stricter and it doesn't compensate like browsers do. https://docs.astro.build/en/reference/experimental-flags/rust-compiler/#expected-differences

I personally dislike omitting closing tags, so it's not a problem for me, but as a maintainer of eslint-plugin-astro, I'd like to confirm this further.

I believe previous compilers intentionally allowed omitting closing tags.
https://github.com/withastro/compiler/blob/main/SYNTAX_SPEC.md#unclosed-html-tags

Has the Astro team agreed to deprecate this going forward?
Or is it simply that the current compiler-rs can't parse them, and users should use the previous compiler if they want to omit closing tags?

---

I prefer the AST generated by compiler-rs, so I want to replace the parser used in eslint-plugin-astro with compiler-rs as soon as possible.
Therefore, if omitting closing tags is to be deprecated, I would like to add a rule to eslint-plugin-astro to check for omitting closing tags so that everyone can migrate quickly.
