Steps to reproduce
Assume that you use Internet Explorer 11 and Enterprise Mode on Windows 8. You have an iFrame a webpage. In this situation, when you click the button to set the iframe display style to “none,” the contents of an ActiveX control or any other control that loads in the iFrame are not hidden. For example, a PDF document in the ActiveX control is not hidden.
I also try to use Div element to wrap the iframe and set the div element to "display: none". Still not working

Thank you for your feedback. We are sorry to hear that you are having difficulties with Internet Explorer. However we’re not presently working on feature bugs in Internet Explorer outside of security-related issues.
Alternatively, if you have a premier support contract you can visit https://premier.microsoft.com and open a support incident and work with an engineer to address this issue.
