In IE, when iframes are being added to the page, the GOPN function throws with"Access is denied".

Screenshot

How to reproduce

1. Go to https://jsbin.com/pafazegato/edit?html,output
   (I used a reference do a dummy doubleclick host, as my issue occurs when tags are being added to the page)
2. Open up the preview in IE, and open up dev tools
3. Make sure to refresh the page to see the "Access is denied" errors

Remarks

• I suspect that this only happens when opening up the dev tools. As getOwnPropertyNames is being used by the dev tools themselves.
• I'll send a PR later on today where I wrap the GOPN function (get-own-property-symbols.js#L125) with a try/catch.
