@russellwheatley Thanks for working this quickly! any idea when this will land in firebase_auth_web on pub.dev?

Anecdotally, ever since the JS Interop updates for firebase_auth it seems like things got a bit unstable. Felt like every couple of days I was chasing another odd auth related bug. Hopefully this is one of the last outstanding issues!
