Steps to Reproduce Bug:
1. Create an app with a WebView opening a web site that uses WebGL, for example, webglreport.com
2. The web site will detect WebGL as not supported / disabled
3. Open the same website from Chrome; WebGL is supported.

Expected Behavior:

WebGL should work in web pages invoked from a WebView when using the emulator, as it does from Chrome.

Observed Behavior:

In the same system and emulator, WebGL works in web pages invoked from Chrome, but not from a WebView.
