Html/css Renderer For Metro-style Apps

The current WebView for Metro-Style apps is unusable for me because it is hosted in a seperate HWND, making it impossible to overlay the WebView with other controls. Additionally,

Solution 1:

Have a look at LibRocket or Awesomium. They're in the right ballpark.

Solution 2:

The new WebView in Windows 8.1 has solved all of the issues I previously had. Mixing the new WebView in XAML apps can be done without any airspace issues (even multiple WebViews can be placed over each other). Since none of the mentioned solutions really solve my issue (not compatible with Metro-Style apps), I have choosen to answer my own question for other people looking for information.
