Chrome on Android deep link handling

Current deep link redirection at OAuth is odd in Android Chrome: it navigate to previous page before redirecting to app. Ideally it should freeze at the same page/empty page.

Start by tracing the OAuth deep-link redirection path for Android Chrome in this repository; the issue does not name a file, test, or entry point. Reproduce the current navigation behavior and identify the relevant redirect handling. Done means Chrome remains on the current or an empty page until the app redirect occurs.
