Safari password generator blocks the password after entry

The Safari password generator when used then blocks the password field with a yellow highlighted box and the words "Strong Password" at the end of the box overwriting the last part of the password it just input into the field. Which makes it impossible to see or copy the password to ensure I can paste the password into another document or incase the password popup to update or enter the username and password into the password keeping in Safari in case it doesn't work. Which, it doesn't work half the time and now you have ZERO idea what the password was you entered because it was block completely.

This happens on every site I go to. The functionality of the password keeper updating and detecting a new password has been entered or a new sign up for a website with username and password is marginal at best if it will actually work once you hit the submit button on that page. It's a cruel game of Russian Roulette.

I've attached a screen shot of what happens every single time the password generator is used on a website.
