title: Edge Chromium giving Failed to read the 'localStorage' property from 'Window': Access is denied for this document
body: <p>I am trying to embed a Google Data Studio report in an iframe for a static site.
  When opening that static site, in Edge Chromium 83.0.478.37 I recieve this error and the data studio report does not appear. It is a clean default install of Edge Chromium, with no settings modified.</p>
  
  <pre><code>Tracking Prevention blocked access to storage for https://datastudio.google.com/embed/reporting/&lt;urlofreport&gt;.
  
  error:
  datastudio__en.js?cb=312620414:3587 ERROR DOMException: Failed to read the 'localStorage' property from 'Window': Access is denied for this document.
  </code></pre>
  
  <p>I've found <a href="https://www.chromium.org/for-testers/bug-reporting-guidelines/uncaught-securityerror-failed-to-read-the-localstorage-property-from-window-access-is-denied-for-this-document" rel="nofollow noreferrer">this information</a>, but in my Edge Chromium, that setting is disabled:
  <a href="https://i.stack.imgur.com/QPYmy.png" rel="nofollow noreferrer">Disabled block third-party cookies</a>.
  The thing that seems to work is to add an Exception in the "Privacy and services" tab in Edge Settings for the domain embedding the iframe. This seems unneccessary, especially when the same static site works on newest versions on both Chrome, Safari, Opera and Firefox. It also seems unnecessary when Data Studio support <a href="https://support.google.com/datastudio/thread/9269345?hl=en" rel="nofollow noreferrer">suggests</a> to use newest Edge. I don't recieve this error when opening the Data Studio report directly in a tab</p>
