I don't think the implementation of Google Universal Analytics is 100% correct. Google may have changed their code recently since this is kind of new...
If we look here:
There's a line not included in the mojoPortal code.
Currently we can't get a site to validate as accurate to Google, and we believe from our research it's the displayfeatures line causing the problem.
I know we could just override the mojo tags.... but I try to avoid overriding mojo functions when possible, just cleaner.
