The UI is not behaving as expected (based on comment in code).
Repro:
1) Open ChromeOS
2) Go to chrome://settings
3) go to lock-screen, observe a dialog prompting for password appears
4) type an incorrect password
5) submit. Observe that the input is invalid and shows error message
6) type 1 more character in the password field. Observe submit button
Actual: the submit button is disabled, even though the input has changed and is no longer invalid.
Expected: the submit button should be enabled as soon as input value changes.
