*
* WebView on Android 4+ automatically scrolls past the title view using this method.
* It looks like user-triggered scroll operations don't call this method. So we use
* it to override the initial scrolling past the title view.
*
* It's a dirty hack and we should find a better way to display the message header. When
* testing this I saw up to two calls to this method during initialization. To make
* sure we don't totally cripple the WebView when the implementation changes we only
* override the first three scrollTo() invocations.
