Hi @glumb, thanks for reaching out to us and providing a good description of the behavior you've encountered. I was able to replicate this and the key point that you mentioned that it only happens when connected to the emulator was spot on. I'll be tagging this as reproducible and will raise it to our Auth team. I cannot make any promises on if and when we will get this fixed; however, it's on our radar.

Hi @jbalidiong thanks for the feedback. TBH this caused some headache on our testing side, as we run the tests in CI against the emulator and were seeing failed tests there, which were passing on the live system.

So even though its "just in emulation" I want to say that having the emulator behave as similar to live as possible seems quite important as it's an extremely valuable tool.
