[Mediawiki-l] Template is closing unclosed tag (e.g. DIV)

I see that there was some discussion about this back in 2006 Jan, but I 
haven't been able to locate a solution anywhere.

What I'm trying to do is to have a template {{Template:Header}} that 
has, say,
<div style="border: 1px solid red;">
and then a template {{Template:Footer}} that closes that div:

Then on my page I want to do this:
some content

When I do this, it auto-closes the div before "some content", which is 
not what I want.

As other people have pointed out, it does work on the Wikimedia sites. 
(I did the exact same thing on http://www.mediawiki.org/wiki/Sandbox and 
it worked.)

In fact, 100s of portals use this technique on Wikipedia (see 
<http://en.wikipedia.org/wiki/Portal:Mathematics/box-header>, for 
example) so I know it can be done.

I'm using the latest version and all (1.9) on my installation, so what 
does Wikipedia have set up differently that allows this?

If someone could tell me how to enable this (or disable auto-closing of 
unclosed tags, as the case may be), please let me know.
