172217 - parsing/layout problem with mismatched tags

Status: RESOLVED WONTFIX

(Core :: DOM: HTML Parser, defect)

Description

[Dan M]

Go to byronhoyt.com in Mozilla. Ewwwwww. That's probably not how the authors
intended it to look. Try it in IE. Very nice.

It's a very challenging-looking page to render, clearly hand-tooled, and full of
unclosed and mismatched tags. Nevertheless, IE handles it fine. Mozilla handles
it fine except for one very deadly set of mismatched tags that go like this
(around line 285 of the HTML):

<ul>
  <li>Band/Orchestra
  <table>
    <tr><td>Popular</td>
</ul>
    </tr>
  </table>

It's the misordered closing of the ul and table tags that causes the problem.

It's understandable, making a mistake rendering this page. But this page looks
fine in IE. IE seems to close out the <table> when the enclosing <ul> closes; we
seem to keep the <ul> open forever.

The nice folks at Byron Hoyt have fixed their website, so this is no longer a
test case.

Attachment: Example as testcase

Adding testcase. And this is confirmed compat; you can't omit the end-tag for
table (even assuming we'd drop the mismatched end-tags).
