Why we can click login button multiple times

Question

We are using Microsoft Oauth2.0 for our app. It shows 'Stay signed in' page.
In this page, we can click Yes and/or No multiple times. When I click No twice after few seconds, same request is post.

We are preventing the login if same request came to block replay attack. So user fails to login.
Is there any way to restrict to click the buttons multiple times?
