Root Account username overwritten with blank

[icompuiz]

Task: Set root password
Expected behavior: password is successfully changed, but other fields remain unmodified unless explicitly modified.

Actual: password did not meet security requirements and username field was blank when the form reloaded. When a valid password and confirmation were submitted the blank username field was also sent and seemed to overwrite the existing value.

When trying to log in using the account name root, authentication would fail.
