Wordpress 2.1.2 strips closing P tag causing xhtml validation to fail

[jayp]

I noticed a bug that I did not have prior to version 2.1.

I have an object tag (flash movie) wrapped around a P tag that provides formatting. I'm not using the WYSIWYG editor. The code looks like this:

<p class="center"><object type="application/x-shockwave-flash" style="width:425px; height:350px" data="http://www.youtube.com/v/T2Bsu4z9Y3k"><param name="movie" value="http://www.youtube.com/v/T2Bsu4z9Y3k"></param></object></p>

But when Wordpress prints this out in the template, it strips the closing P tag and adds a few line breaks (perhaps no big deal). Viewing the source code reveals this:

<p class="center">
<object type="application/x-shockwave-flash" style="width:425px; height:350px" data="http://www.youtube.com/v/T2Bsu4z9Y3k">
<param name="movie" value="http://www.youtube.com/v/T2Bsu4z9Y3k"></param>
</object>

The page no longer validates as proper xhtml. But if I save this html locally and add that closing P tag manually, it will validate.

I'm quite certain this never happened before 2.1.

This is my first time using trac so please forgive me if I've done something wrong. Incidentally, this issue may be somewhat related to ​Ticket 3669.
