Is it possible to disable the IE patibility mode from within an Iframe?

If I use the following meta in the iframe html, this not working:

<meta http-equiv="X-UA-Compatible" content="IE=11; IE=10; IE=9; IE=8; IE=7; IE=EDGE" />

• It's the same problem: "I want to <do something> to the document including me via an iframe" with the same answer: You cannot do that unless you own the document that contains the iframe. – André Dion Commented May 1, 2015 at 16:25

It depends on if you have access to the x-ua-patible meta of the host (parent). When the host page is at IE9 mode or above, its state is imposed on the iframe. Here's a good explanation, given by a moderator at MS-Connect.

Here's supplemental info about how Quirks mode forked two ways beginning with IE10.

Here's a live demo which allows changing the IE modes on-the-fly.
It was patched to also allow selecting the iframe url.
