I'm not clear if this makes sense to be on the WKContentView.  I believe there are some PDF related issues with that.  I need to check with Tim/Andy.

This should be YES.

> +    _isBackground = FALSE;

This should be NO.

I checked with Tim, and this is not an issue in this case. The problem was depending on WKContentView to always be parented (which in the PDF case it is not), but since we don't care about parentage in this case, it doesn't matter.  r=me.

Probably at some point we should move those notification listeners to WKWebView, but not today. I think this is fine.
