When merely opening artstation.com 1PasswordX shows its UI even though no login form is visible.
A similar issue happens on Android. It looks like they are hiding the login form using
opacity: 0; pointer-events: none; CSS and it ends up being focused by default on page load (this can be confirmed by typing something right after opening their page - anything you type ends up in the email field).
I think a good solution for the extension would be to not act on forms that are inside a container with opacity 0.
