Set password form not styled correctly

Hi,
I have a problem on the new user set password page/form. The Login and Register Page looks fine, but the form that the user sees when he gets a link to set his password is not styled correctly.

I found another topic from your plugin, where it says this bug should already be fixed (https://wordpress.org/support/topic/new-user-generate-password-page/) but it seems still broken. I am not sure if that’s the exact same bug though.
