admin login form 1Password autofill issue and attr placeholder suggestion

[tgressly]

In the first attempt 1Password enters the value of 'user_name' in the field 'user_name' AND as well in the field 'password', and it is not submitting the form although autosubmit is turned on. The second attempt however, always succeeds in all of the necessary steps. Odd.

Reproducible on Firefox and Chrome Mac. Others not tested.

1Password version is 3.8.21. Maybe with 1Password 4 it would work. Cannot test this.

While fixing this issue, please consider to use the input field's attribute 'placeholder' instead of the existing JS solution with 'value'.
