When using the Jenkins user database, it is not possible to sign up for an account if one enters the password other than by typing it.

Steps to reproduce (on Firefox, other ways surely exist)

1. Configure Jenkins to have the Jenkins user database with signup enabled.
2. Go to /jenkins/securityRealm/createAccount
3. Enter username, name, email if necessary
4. Right-click the password field and let Firefox suggest a strong password.
5. Press Create Account

Expected Result

It works

Actual Result

Password field validation fails with the error

Password - Password didn't match

There's no second password field that couldn't match! (Well, it's a hidden form field that's synched via JS for some reason.)
