Auth.signIn request at the same time generate same jwt token with different accounts

Describe the bug When submit two request to method await Auth.signIn(username, password) at the same time with different accounts, the method generate the same token (signInUserSession.accessToken.jwtToken);

To Reproduce Steps to reproduce the behavior:

1. Use the method await Auth.signIn(username, password)
2. Make two requests with different accounts at exactly the same time
3. get the function’s return and go to: signInUserSession.accessToken.jwtToken
4. and you will see that the generated token is the same for different accounts

I was able to reproduce this behavior, which definitely appears to be a race-condition:

• Signing in separately returns different tokens (e.g. even a second or two apart).
• Signing in simultaneously returns the same jwtToken:

So we can help prioritize this issue, can you provide some detail on why two separate user accounts are being signed in simultaneously? Thanks!
