31970	Logging in from one browser logs me out from other browsers (after any change in PBKDF2PasswordHasher.iterations)	אורי	nobody	"- I upgraded Django from 3.0.6 to 3.1.1 with `DEFAULT_HASHING_ALGORITHM = 'sha1'`.
- I was logged in from several browsers.
- The first time I login from a new browser with Django 3.1.1, all my other sessions expire, and I'm automatically logged out from all the other browsers.
- This happens only once, at the first time I login with Django 3.1.1.
- I think it's a bug, since users may use several browsers and they don't need to be logged out when they login from a new browser.
