This is just creating a global object "WebGL" containing an object using
the WebGLActiveInfo interface.  It's not moving the WebGLActiveInfo
interface itself into an object.  It sounds like you want something like

interface WebGL {
    interface WebGLActiveInfo {
        ...
    }
}

interface WebGLRenderingContext {
    WebGL.WebGLActiveInfo? getActiveAttrib(WebGLProgram? program, GLuint
index);
}
