Confirming exactly as described in comment 0 and comment 6, except for freeze/hang.

Simplified STR

1) Have email address `johndoe824@gmx.de` (primary), with an alias on mail server: `johndoe824second@gmx.de` (alias). On server, that's one account with one password and two email addresses / user names.
2) Use TB account wiz to set up POP account for the alias: `johndoe824second@gmx.de`, do **not** `Remember password` (for existing TB account, delete all account passwords in pw manager).
3) In `Account settings > ... > Server Settings`, **change `User Name` to `johndoe824@gmx.de`** (primary user name, now different from alias email address, which is default identity of the account).
4) Press F5 to get messages, get `Enter your password for johndoe824@gmx.de` (do it!), check `Use Password Manager to remember this password`.
5) Check out the actual user name saved in `Options > ... > Saved Passwords`

Actual Result:

`Saved Passwords`:
- Provider: mailbox://pop.gmx.net (mailbox://pop.gmx.net)
- Username: `johndoe824second@gmx.de` (stale user name because we changed that before saving password; is it using the email address?)

Expected Result:

`Saved Passwords`:
- Username: `johndoe824@gmx.de`

Weirdly, when you actually change the username in `Saved Passwords` to match the user name used by the account, it will then ask for the password.
