When logging in, in most cases a second captcha is presented

Similar to this thread, more often than not the first captcha fails.

Can we make it so that first captcha entered correctly is enough?

I understand eventually the server might want a second captcha if it’s not convinced the user is not a robot even if they entered the first one right. But it’s too frequent. And, more interestingly, if we hit the refresh captcha button, the second captcha presented works immediately. No need for a second try.
