title: msal.js: acquireTokenSilent does not work with Internet Explorer 11
body: <p>I am working on a project authenticates users with azure active directory. Fetching the user token works fine, I get all user information. But when I try to acquire an access token via acquireTokenSilent, I get the following error:</p>
  
  <pre><code>"AADSTS50058: A silent sign-in request was sent but no user is signed in."
  </code></pre>
  
  <p>It works fine for every other browser. </p>
  
  <p>To add my website to the "IE security zone" as suggeste in this <a href="https://github.com/AzureAD/azure-activedirectory-library-for-js/issues/323#issuecomment-466035718" rel="nofollow noreferrer">issue</a> is not possible unfortunally due to the policy of my company. </p>
  
  <p>Edit: Setting the <code>storeAuthStateInCookie</code> as Allen Wu suggested only solved the problem of getting no login token. Unfortunally, I need an access token via acquireTokenSilent to authenticate with my backend. Gaterhing an access token works with every browser but Internet Explorer. Sorry, I hope that cleared the question.</p>
