Client side JavaScript Google Sign In stopped working in Safari for Mac OS X v.10.15.2

After upgrading to Mac OS X version 10.15.2 sign in to Google with the google-api-javascript-client library has stopped working for some users in Safari.

The Safari developer console and network tab doesn't really tell me much regarding what the issue is for that specific Safari version.

Example snippet

<script src="https://apis.google.com/js/platform.js" async defer></script>
<meta name="google-signin-client_id" content="REPLACEME.apps.googleusercontent.com">
<div class="g-signin2" data-onsuccess="onSignIn"></div>
<script>
function onSignIn(googleUser) {
  var profile = googleUser.getBasicProfile();
  console.log('ID: ' + profile.getId()); // Do not send to your backend! Use an ID token instead.
  console.log('Name: ' + profile.getName());
  console.log('Image URL: ' + profile.getImageUrl());
  console.log('Email: ' + profile.getEmail()); // This is null if the 'email' scope is not present.
}
</script>
