      Changed Status to “Fixed”

    • Hello,

      Thank you for the feedback on Internet Explorer. We are not working on IE feature bugs any longer unless they are security related. I tested out this repro in Edge 10586 and saw the same behavior.  However when I tested this out with our insider builds (14342) I noticed the opposite - the page works as expected.

      As a result of this testing the item will be closed out as fixed. We welcome any feedback you have in the future regarding Edge.

      All the best,
      The MS Edge Team
