Embedding a Word/Powerpoint/Excel document gives an error message

I'm embedding an office document in a WebView in a Windows 8 application, and I'm getting an error. To reproduce, simply create a C# Windows 8 Store application and add this element to the grid:

<WebView src="https://onedrive.live.com/embed?cid=D8B2810BB4536B61&resid=D8B2810BB4536B61%21881&authkey=AMZzHPItHSnzgYg&em=2&wdStartOn=1"></WebView>

This is the error box I'm getting. I get the same error embedding an Office365 document. I've submitted a bug report using the link. Is there any way to get more information on this error?
