[Problem/Bug]: Find popup can no longer open after the Form is reshown after being hidden while the Find popup was showing

[pushkin-]

What happened?

1. if I have a Find popup showing and the WebView2 control is hidden, the Find popup is hidden
2. If I hide the Form that owns the Find popup (and optionally the WebView2 control afterwards), the Find popup stays visibile
3. If I switch the order and hide the WebView2 control before the Form, the Find popup disappears, but when the Form is reshown, Ctrl+F no longer shows the Find popup (i.e. the StartAsync API is broken)

Repro steps

Download the minimal webview2 WinForms sample

To WebView2Control_CoreWebView2InitializationCompleted in BrowserForm.cs, add:

this.webView2Control.CoreWebView2.Settings.AreBrowserAcceleratorKeysEnabled = false;
this.webView2Control.KeyDown += WebView_KeyDown;

And define the handler like so:

		private void WebView_KeyDown(object sender, KeyEventArgs e)
		{
			var wv2 = (WebView2)sender;
			if (e.KeyCode == Keys.F && Control.ModifierKeys.HasFlag(Keys.Control))
			{
				e.Handled = true;
				DoFind(wv2);
			}
			else if (e.KeyCode == Keys.F12)
			{
				e.Handled = true;
				wv2.CoreWebView2.OpenDevToolsWindow();
			}
		}

		private void DoFind(WebView2 wv2)
		{
			var findOptions = wv2.CoreWebView2.Environment.CreateFindOptions();
			wv2.CoreWebView2.Find.StartAsync(findOptions);

			Task.Delay(2000).ContinueWith(t =>
			{
				this.Invoke(() =>
				{
					ToggleVisibility(wv2, false);
				});
				Task.Delay(2000).ContinueWith(t2 =>
				{
					this.Invoke(() =>
					{
						ToggleVisibility(wv2, true);
					});
				});
			});
		}

		void ToggleVisibility(WebView2 webView2, bool visible)
		{
			webView2.Visible = visible;
			this.Visible = visible;
		}

1. start app
2. press Ctrl+F and type some stuff in there optionally
3. After 2 seconds, the Form will hide along with the Find popup
4. After 2 more seconds, the Form will reshow
5. Ctrl+F will no longer open the Find popup

A related issue is that while the Find popup is no longer visible when the window is reshown, the previous search highlighting it still shown.

For example, Ctrl+F for "a" in google.com, hide window, show window, Find popup is gone and can't be brought up again, but I see:

Press Ctrl+F (which will trigger a call to StartAsync) will remove the highlighting.

I also encountered the same problem, it seems that the find popup is covered.
When I encounter this situation:

1. press the ESC key (the find popup will be cancelled at this time).
2. press ctrl+f to display find popup.

This has been fixed in version >= 137.0.3291. @pushkin- , @Memoyu , can you please verify if you are still seeing this issue in versions greater than the version with the fix.
