Disable all errors on Cefsharp WinForms #4436

Let's say I have this following proof of concept webpage:

<html>

  <body>
    <h1>Hello</h1>
  </body>


<script>
console.log("hahah")
z
</script>
</html>

If I open this page with CefSharp browser, I get the following message in the bottom left corner of the screen:

Now, this would be fine and helpful in development use, but in production use, I'd like to disable all errors visually.

I tried overriding the IJsDialogHandler and the OnJSDialog method like this:

        public bool OnJSDialog(IWebBrowser chromiumWebBrowser, IBrowser browser, string originUrl, CefJsDialogType dialogType, string messageText, string defaultPromptText, IJsDialogCallback callback, ref bool suppressMessage)
        {
            suppressMessage = true;
            return false;
        }

But I still get the same error messages.

So the question is, how would I go about overriding the behavior and disabling ALL JS error messages?

Thanks in advance!

If I open this page with CefSharp browser, I get the following message in the bottom left corner of the screen:

ConsoleMessages aren't displayed by default, it's up to the embedding application to actually show them.

The image you've shown looks a lot like the MinimalExample which shows the messages for demo purposes.
