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

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

Blocking. My app's basic functions are not working due to this issue.

2. Open form with size default of form (512x512) -> No 3 dots appear.
