Taking a look to find out why the smartblock placeholder button isn't working.

The site seems to be using setPointerCapture to capture clicks and fails to forward the click to the embed placeholder. I've submitted a patch that blocks setPointerCapture calls on just the our placeholder elements.

I've also built a simplified demo page here that captures clicks and breaks the embed placeholder button in a similar way like the page in this bug: https://playground.emz.im/embed-disqus-pointer-capture/
