[Problem/Bug]: When hiding toolbars Print, save, save as, full screen, rotate with HiddenPdfToolbarItems, 3 dots appear even though they are not active

[thanhbao1996]

What happened?

CoreWebView2.Settings.HiddenPdfToolbarItems = CoreWebView2PdfToolbarItems.Print | CoreWebView2PdfToolbarItems.Save | CoreWebView2PdfToolbarItems.SaveAs | CoreWebView2PdfToolbarItems.FullScreen | CoreWebView2PdfToolbarItems.MoreSettings | CoreWebView2PdfToolbarItems.Rotate;

// On winform, when applying the above setting, if you minimize the form, the 3 dots appear even though it does not work. I think it is a problem because if there is no activity, it should be hidden to avoid misunderstandings

Importance
