User Profile not created

[Velenir]

In a webapp, when multiple users log in/log out one after another, only the first user receives a full User Profile in Mixpanel dashboard.

The flow:

1. App is loaded
2. mixpanel.identify(user1)
3. POST request to https://api-js.mixpanel.com/engage/ happens
4. mixpanel.reset()
5. mixpanel.identify(user2)
6. No POST request to /engage

Afterwards I only see User1 in the Mixpanel dashboard for Users with Profile, User2 doesn't have its profile filled in (most notably with location data), even though all its tracked events contain that kind of data.

It seems to me that after the first reset() call (including if I call reset() before the first identify()) , no more calls to /engage and no more full User Profiles happen.

Am I doing something wrong? Is there a bug in mixpanel-js?

Here's a sandbox with a reproduction
