// Before loading a URL corresponding to this WebUI, the caller should set its
// delegate as user data on the WebContents by calling SetDelegate(). This WebUI
// will pick it up from there and call it back. This is a bit of a hack to allow
// the dialog to pass its delegate to the Web UI without having nasty accessors
// on the WebContents. The correct design using RVH directly would avoid all of
