title: MSAL: Why is setting the redirectUri to a blank page recommended?
body: <p>I'm reading this document: <a href="https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/lib/msal-browser/docs/initialization.md" rel="nofollow noreferrer">https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/lib/msal-browser/docs/initialization.md</a></p>
  <p>It is written that:</p>
  <blockquote>
  <p>When using popup APIs we recommend setting the <code>redirectUri</code> to a blank page or a page that does not implement MSAL. This will help prevent potential issues as well as improve performance.</p>
  </blockquote>
  <ol>
  <li>What are &quot;potential issues&quot; and &quot;performance&quot;?</li>
  <li>If I set the <code>redirectUri</code> to a blank page, is the user redirected to the blank page?</li>
  </ol>
