CefSharp Executing JavaScript from C#

I'm beginning to mess with CefSharp, but unsure if the behavior I am seeing is avoidable. I am attempting to execute rapid fire JavaScript statement to simulate animations to see if the refresh rate will be good enough for the project use. I've got a grid of some squares, and I would expect that I would see the colors changing rapidly, but all of the changes happen after the loop has finished, with just one refresh instead of many.

    public void start()
    {
        Random random = new Random();

        int x = 0;
        while (x < 5000)
        {
            string num = random.Next(16).ToString();
            var script = String.Format("document.getElementById({0}).style.backgroundColor = colors[Math.floor(Math.random() * (2 - 0 + 1)) + 0];", num);
            ExecuteJavaScript(script);
            //MessageBox.Show("");
            x++;
        }
    }

    private void ExecuteJavaScript(string script)
    {
        this.webView.ExecuteScript(script);
    }

What is going on with ExecuteScript that it is waiting for operations to complete before refreshing?

Thanks in advance for any help!

I've managed to get the desired results by creating a global JavaScript function, and calling the function from ExecuteScript() and in the global JavaScript function, calling start() for a constant loop.
