Answer 1

Default display to protect from the others knowing the length of your password

Answer 2

I think there is rather the behaviour of a browser for saved password, not control by web codes, to disable others from knowing the length of the saved password.

Answer 3

It's just the way it mask the password, the extra characters do not exist.
