 Hello,

 I noticed an issue with IE11 iframes ignoring zindex and overlapping the
 WP Admin Bar, screen;

 In the screen we see an iframe with no z-index or absolute positioning
 overlapping the admin bar when scrolled down.

 More info on this bug in IE;

 The solution is to basically inject an empty (about:blank) iframe into the
 container for the wpadminbar for IE.

 Let me know if I can help with clarifying or troubleshooting, etc.
 Thanks
