When arriving to Password Reset page from Password Reset Request email link, username is the wrong one

[fontanka16]

Steps to reproduce:

1. Go to the login page of your Grav installation.
2. Hit the Forgot button
3. Enter the email of user A, click the Send reset instructions button
4. Open the email, Click the link

What should happen:
You get to the page allowing you to set a new password with your username after the Username: placeholder.

What actually happens
Occasionally, Grav gets stuck on displaying another user's username. It seems to be tied to users that has previously reset their passwords.

Additional info
I have had two users reset their passwords interchangeably, and some times their own username shows, and some times the other's. The reset works flawlessly though.

Is it possible to hide the Username alltogether as a workaround?
