* Add isTopFrame to shouldStartLoadForRequest on iOS onLoadingStart is not raised for inner frames, but onShouldStartLoadWithRequest still is. This keeps that behavior but adds isTopFrame to onShouldStartLoadWithRequest so that apps can perform their own filtering if desired. * Update docs Co-authored-by: Jamon Holmgren <jamonholmgren@gmail.com>
