I can confirm the repo with hiding the bookmarks. Others (like hiding search) works fine, tool bar shows, and the search icon hides. Can you recheck if the problem as I described?

If I uncomment any of the commented lines below the pdf toolbar disappears.

viewer.CoreWebView2.Settings.HiddenPdfToolbarItems = //Microsoft.Web.WebView2.Core.CoreWebView2PdfToolbarItems.Bookmarks | //Microsoft.Web.WebView2.Core.CoreWebView2PdfToolbarItems.Search | Microsoft.Web.WebView2.Core.CoreWebView2PdfToolbarItems.FullScreen | Microsoft.Web.WebView2.Core.CoreWebView2PdfToolbarItems.MoreSettings | Microsoft.Web.WebView2.Core.CoreWebView2PdfToolbarItems.PageSelector | Microsoft.Web.WebView2.Core.CoreWebView2PdfToolbarItems.PageLayout | Microsoft.Web.WebView2.Core.CoreWebView2PdfToolbarItems.Save | Microsoft.Web.WebView2.Core.CoreWebView2PdfToolbarItems.SaveAs | Microsoft.Web.WebView2.Core.CoreWebView2PdfToolbarItems.Print;

So this is about hiding Bookmarks and/or Search

Thanks for providing the details. It's confirmed and we'll track this issue. But now, I see the problem should be - Toolbar disappears either hiding all left side (bookmarks) or right side (Search, FullScreen, MoreSettings, PageSelector, PageLayout, Save, SaveAs, Print) icons.

Do you agree this is the correct description? And please edit the title and main content. @setniessesed @victorhuangwq
