Styling is stripped from "<PRE>" elements when rendered.  

I've tried to create a special CSS style to use to show code or commands entered
on a screen.  In MediaWiki:Monobook.css, I've added the selector '.sn-screen {
font: normal 100% "Courier New", monospace; background: #DDD; padding: 8pt }'. 
In my pages, I use '<pre class="sn-screen"> stuff </pre>'.  What actually gets
output to the browser is '<pre> stuff </pre>'--the class, and hence the
associated formatting, is stripped out.  

Other elements don't have this problem.  For example '<p class="sn-screen">' is
output as expected.  

As a workaround, I defined the default formatting for <pre> to be what I want
for screen output ... but then ALL <pre> formatted elements come up the same,
which really isn't what I want.
