Fixed #13316 -- Modified the default behavior of PasswordInput to prevent reflecting passwords on form failure. Thanks to clouserw for the report.

Although this changes nothing at a functional level, this is BACKWARDS INCOMPATIBLE from a UX perspective for anyone that wants passwords to be reflected to the user on form failure. See the 1.3 release notes for details.
