Masking a 'password' type input makes the field appear prepopulated

[SladeRun14]

Applying a mask to a password type input field confuses the user

Use case:

We're trying to apply a mask to field that accepts a PIN number. The PIN number should be hidden from onlookers as the user types, so we use a password type input field. We want to limit the user to entering exactly 6 digit and only digits. The mask is perfect for this (paired with a validation).

• Feature request
• Code refactor
• Continuous Integration (CI) improvement
• Changes in documentation (docs)
• Other (describe)

What is the current behavior?

Applying a mask to a password type input field initially displays the field populated dots. These dots erroneously indicate to the user that something has been entered in the field.

What is the expected behavior?

A password type input field should initially display the underscores representing each digit in the mask.

It is beyond us to change how the input type password displays the inputted characters on the navigator.

The desired use case will be feasible though, when #55 is done (and using input type text).
