Summary:**Motivation:** In my app, I'm using a WebView that loads content from my mobile site. What I want to do is when a user presses a link on the loaded page, I want to stop the WebView's request, hijack the URL and open the URL in a new WebView, pushed to the top of the navigator stack. To me, this gives the overall app a more native feel, instead of implementing a rudimentary navbar on the main WebView to go back.
**Attempted Workarounds:** I've attempted to get similar functionality by capturing the onNavigationStateChange event in the WebView, and then within calling goBack + pushing the new view to the navigator stack. From a functionality standpoint, this works. However, from a UI standpoint, the user can clearly see the webview change states to a new page + go back before having the new view pushed on top of their nav stack.
