I think Pandora itself could be doing something to affect this (intentional or not). I set permissions in the manifest to load RE on all websites, and the icon appeared as expected in all except Pandora. Icon appears on Pandora.com until the loading screen disappears. The icon can be re-applied afterwards, but I don't like that solution.
