getContext("experimental-webgl") fails

[JimSEOW]

var ctx = document.createElement('canvas').getContext('experimental-webgl');

What needs to be done to make that works?

    `public object getContext(string contextType)
    {
        if (contextType == "2d") {
            if (this.context == null) {
                this.context = new CanvasRenderingContext2D(this.window, this);
            }
            return this.context;
        }
       else if (contextType == "experimental-webgl")
        {
            if (this.context == null)
            {
                this.context = new CanvasRenderingContext2D(this.window, this);
            }
            return this.context;
        }
        return null;
    }`
