Space is silently ignored when entering a password on the web app

[aldem]

🐞 Describe the bug

While spaces in passwords are accepted (for instance, when adding a user), the web app silently ignores them during sign-in while you type.

To actually enter a space in the password, you must type the entire password and then insert spaces where necessary by editing the password.

However, this still does not permit a space to be used as the very last character.
