Violating security check on createElement("object")

[AndreyChernykh]

I use webcomponents in my page for my Microsoft Office Task Pane Application. It uses Internet Explorer & Edge to render the pane. But because of

// webcomponents.js 
var elementsWithFormProperty = [ .... HTMLObjectElement, .... ]

and

// webcomponents.js 
var elements = {
...
object: "HTMLObjectElement",
...

pane shows security warning:

an add-on for this website failed to run. check the security settings

Possible solution:
If the browser is IE, do not create HTMLObjectElement

Thanks for the issue. It has been a great while since this issue was opened. Sadly, this issue misses a live reproduction with the most recent version of the webcomponents polyfill for us to be able to debug and potentially fix. Versions 1 of the polyfills fix a large amount of issues, probably including this one as well.

Please see the CONTRIBUTING.md for guidelines on filing issues. You can start from this jsBin template as a starting point and link it in the issue template under "Live Demo".

Feel free to file a new issue following these instructions if you can still reproduce this issue with versions 1 of the polyfills. Thank you!
