Default allowed CSS array

Issue Summary

I was using taxonomy panels to take over my taxonomy pages.
The title is build out of all term names, seperated with a , or +.
I wanted to capitalize the title, but cannot find a class or id selector to use in my theme.
The first mention of a page id, set by panels or any indication that I'm on a taxonomy panel page, is only given when the inner content is rendered.
So I added a css in the 'general' section of my taxonomy panels.

However "text-transform: capitalize, uppercase, lowercase or inherit" is filtered out by chaos suite.
I can't find a reason why it should. Can it be added to the default allowed list of css.

thx
