The dialog sets the password to all password fields on the form

After entering password hashing settings and clicking the Ok button of the dialog, the generated password is set to all password fields on the page. This is clear in this piece of the content.js file where all password fields are iterated and have their value set to the generated password, although input_id is sent to the dialog and should be used to set the password to the correct target.
