Hi,
I am working on resolving a bug in Mathjax(www.mathjax.org) that I use inside mediawiki. Using Internet explorer 8 mathjax renders some math markup wrong. The fix for this issue is to force IE 8 to use IE 7 rendering mode via a meta tag. I managed to add the meta tag to the head element by doing this:
$out->addHeadItem('Meta',' <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7">');
The problem is that this puts in to the bottom of <head>. Is it possible to put it as first in the list of <meta> tags? This must be the first <meta> in order to make it work.
