Thread:Extension talk:Header Tabs/Response headers for css does not contain a content-type

I noticed while enabling gzip compression on my wiki that the skins/ext.headertabs.large.css file is not being sent down with a content-type in the HTTP header. This is preventing it from getting properly compressed by my mod_pagespeed configuration, which identifies content for compression based on the content-type.

I'm not sure if there's something specific that needs to be done within the extension definition to set the proper content-type. Thought I'd mention it.
