title: IE 11 cannot set breakpoint in javascript file added to HTML page
body: <p>I have an HTML page that has an embedded javascript file that for some reason or another I cannot debug. I can click on the error line to go to the location in the code but once there I cannot actually set a breakpoint inside the IE 11 debugger. I can however set a breakpoint in the HTML which isn't helpful to me.</p>
  
  <p>I've read similar posts on the topic but they haven't helped. I've unchecked the box that disables script debugging in the IE 11 options.</p>
  
  <p>Does anyone know what could actively prevent the debugging from happening? Even console.log lines aren't making it through...</p>
  
  <p>Thanks.</p>
  
  <p>edit: the exact error I'm getting is SCRIPT1010: Expected identifier on an Object.entries().forEach call that I've already added the necessary polyfills for.</p>
