 The fixed header doesn't work at all in any version of IE. Same issue as
 #23841, probably a similar solution.

 There are three ways we could fix this:
 - Remove the custom header image and do the fixed header with CSS only
 (see also #25094)
 - Use a CSS solution by default and only use the (lengthened/fixed) JS if
 the header image feature is being used (not default) - would also help
 performance of the fixed header for the majority of installs that probably
 won't use the header image
 - Add the additional, reasonably complicated JS needed to make this work
 and always use that even if there is no header image
