[Problem/Bug]: Find Filter button broken when going through StartAsync API

What happened?

When intercepting Ctrl+F and showing the Find popup with StartAsync, the Filter button doesn't do anything.

This works fine when not using the StartAsync API.

Importance

Important. My app's user experience is significantly compromised.

Repro steps

Download WinForms sample app

In WebView2Control_CoreWebView2InitializationCompleted, add: this.webView2Control.CoreWebView2.Settings.AreBrowserAcceleratorKeysEnabled = false;

Update the existing WebView2Control_KeyDown to:

    private void WebView2Control_KeyDown(object sender, KeyEventArgs e)
    {
            var find = this.webView2Control.CoreWebView2.Find;
            if (e.KeyCode == Keys.F)
            {
                var options = webView2Control.CoreWebView2.Environment.CreateFindOptions();
                options.FindTerm = "";
                find.StartAsync(options);
            }
   }

1. start app using Canary Edge
2. press Ctrl+F
3. Clicking Filter button does nothing.
4. If the Filter button were previously toggled on, it will show it but then toggling it off causes issues
