The problem is that this component breaks page rendering for chrome production builds. My current chrome build is: Version 26.0.1386.0 dev-m
A page where the problem can be seen is:
dev.ckoebbeman.com/index.php/portfolios/item/87-fine-furniture
If you load that page in chrome vs. internet explorer you can clealry see how the page header is missing in chrome. In fact, in the production version of chrome (not the dev version I'm using) it's much worse. There, the page header is missing, the menu is pushed to the bottom, and the left margin of the sheet becomes huge.
In other words, this component simply is not usable in a world where chrome accounts for so much browser share.
