Fix toggling between hidden and visible password

Summary:
A previous PR broke toggling between visible and non-visible password (basically once a password field was made visible, future updates to the keyboardType were effectively ignored, so the password would always be visible).

Original PR: #27523

Changelog: [Internal]
