I have noticed that a `webview` will emit the `did-navigate-in-page` event when an IFRAME included in the page finishes loading.

Is this the desired behavior? The documentation implies that this event shall only trigger when the main frame's URL hash changes. In any case, a flag `isMainFrame` would be helpful here.
