[Problem/Bug]: Find:StartAsync clears existing entry on a delay when passing a new FindTerm in

[pushkin-]

What happened?

If I trigger the Find popup and pass in a starting search term like this:

 var findOptions = wv2.CoreWebView2.Environment.CreateFindOptions();
 findOptions.FindTerm = "a";
 wv2.CoreWebView2.Find.StartAsync(findOptions);

It takes a second or so for the previous search term to be replaced by the new one, so there's a moment where the user can still see the old term.

If you set the FindTerm to be longer (findOptions.FindTerm = "aaaaaaaaaaaaaaaaaaaaaaaaa";), the change becomes near-instantaneous.

Importance

Low. My app is not very affected, or this only affects development.

Repro steps

1. open sample WinForms app
2. In WebView2Control_CoreWebView2InitializationCompleted, add this.webView2Control.CoreWebView2.Settings.AreBrowserAcceleratorKeysEnabled = false;
3. In WebView2Control_KeyDown, add this code:

if (e.KeyCode == Keys.F && Control.ModifierKeys.HasFlag(Keys.Control))
{
     e.Handled = true;

         var wv2 = (WebView2)sender;
	var findOptions = wv2.CoreWebView2.Environment.CreateFindOptions();
	findOptions.FindTerm = "a";
	wv2.CoreWebView2.Find.StartAsync(findOptions);

}

1. Run the app
2. press ctrl+f
3. type some text in there
4. close the popup
5. press ctrl f
6. notice the text you typed is still in there and gets replaced with "a" in a second
7. If you make the FindTerm longer (e.g. "aaaaaaaaaaaaaaaaaaaaaaaaa"), the change happens more quickly
