report error for missing closing tag token

[emi2k01]

As you can see, I used abort_call_site instead of adding a more appropriate span like the rustc one:

The reason is that I don't know how.

I don't know how to make this a draft. The test failing is named "element-missing-body" but HTML tags are not required to have a body, I think.

Should I rename the test to non-closed-element?

Thanks @emi2k01! Happy to merge once the comment is addressed (and the tests pass).

Sure, do it!

Btw, do you know if it's possible to create a diagnostic with whose span is just after the last token? Just like the second screenshot I added to the original comment.

Thanks!

There is Span::after, but it's unstable.
