Pull Request buttons and other interactive elements in header being handled

Alright here's the pull request for this. I re-added the header onclick listener and have verified its working. I wasn't sure if I should modify the sample to include a button but if you want me to I can add that as well. I have those changes stashed at the moment. I have noticed one issue that I hadn't realized was happening and thats the press state of button doesn't get honored while the click event is.
