Android reports of failure to authorize w/ Opera

## Issue

I've received several reports this week from users who are unable to authorize using this library on Android, and the common thread seems to be that they are on the latest version of Opera. It seems like the underlying OpenId project that this wraps has some reports about this issue as well.

Curious if other people have seen anything like this. So far I've been unable to reproduce it on a simulator, even when disabling Chrome on the device completely.

## Environment
Android, 8.0 + Opera browser.
Not using Expo.

Start by investigating authorization failures on Android 8.0 with the latest Opera browser, then compare the behavior with the underlying OpenId project's reported issues. Done means the failure is reproducible or its cause is identified, with a verified resolution or a documented limitation.
