Any update on this issue?

The cl that caused this issue got reverted, so it isn't a blocker anymore. An adjusted version of the cl is sitting in review, but I got a higher priority issue I have to work on first and I'm not sure if the adjusted cl will land in M-54. I still want to keep this bug alive for verification when the cl lands, so in the mean time I'll remove the release block label and reduce priority.

let's close this if it's reverted. Just make sure to test the login on device before you land.
