Currently, we mirror `hardwareKeyboardAttached` state between WebKit::WebPage and WebCore::Page by plumbing down from WebKit with a call into Page::setHardwareKeyboardAttached(). Unfortunately, we only propagate this information _once_ during WebPage creation. This means that this information can get outdated when hardware keyboard state changes (i.e. calls into hardwareKeyboardAvailabilityChanged). We should either (a) plug all the holes where hardware keyboard state is not being propagated or, better yet, (b) have WebCore::Page just key off of WebPage state by going through ChromeClient.
