title: IE role="alert" is not read on page load
body: <p>I'm adding accessibility support for my project, and recently find out JAWs doesn't read out element with role="alert" if the element is loaded with page using IE11.</p>
  
  <p>I have a page that submits inputs to server and receive response with error span if no data is available. The error span has role="alert" assigned. The error is read immediately after page load when using chrome, but IE seems to ignore the error. </p>
  
  <p>I can't set the focus to the error span because the focus need to be set to the error caused field. </p>
  
  <p>I'm using JAWs 2019 with IE11.</p>
  
  <p>For a testing example,
  Simplly open a HTML document using IE11 with content:</p>
  
  <pre><code>&lt;h1&gt;title&lt;/h1&gt;
  &lt;span role=alert&gt;this is an alert&lt;/span&gt;
  </code></pre>
  
  <p>In my testing the span is not read out immediately.</p>
  
  <p>Update:
  JAWs 2019 is working fine with other alert elements in IE11 in my testing. It's only when I have an alert element thats loaded with the page when I see a problem. JAWs should narrate the alert element after the element is loaded. Chrome is working as expected.</p>
