John Frizelle Yes, we do plan to raise a PR to upstream when it's ready. At the moment, because everything else goes on, we didn't have time to get the PR ready.

The problem here is that we need to explain to upstream why we need to get the system browser working, even though the current in app browser approach does work on device (am I right Stephen Coady?). For our use case it will be to support SSO. But we first need to verify it is indeed working as we have expected.

In the meantime, I think it's no harm to ask in the KC community if the current keycloak.js supports SSO for cordova apps. Stephen Coady can you do that? If it is not something that is supported at the moment, we will verify this works and create a PR against upstream.
