How to get FirebaseSimpleLogin Facebook login working in a fullscreen/homescreen iOS Web App

Question

I have an angular app that painlessly integrates with Firebase's SimpleLogin service for Facebook on the web, however, it relies on opening a pop-up to do so.

Although iOS 7.0.3 seems to have fixed some severe bugs where alerts and popups were not functional in fullscreen web apps (i.e. after 'Add to Homescreen'-ing a website via Safari), the Facebook login fails after redirecting to Facebook and granting approval, landing back on a blank page (which requires an app restart to remove).

I suspect this has something to do with the was Facebook is redirecting back, but AFAIK I don't have control over that, nor would hacks like these fix this.

Are there any workaround that exist for this problem?

[Engineer at Firebase] Support for redirect-based OAuth has been added to the Firebase Simple Login Web Client as of v1.3.0, available from the Firebase CDN or via Bower using bower install firebase-simple-login.

This update enables the Firebase Simple Login client to detect iOS "standalone" applications and handle the redirect-based OAuth automatically in your application.
