404 (Not Found) bootstrap5.css after update to v20.1.0.47

[Dennis M]

I'm using NuGet Syncfusion.Blazor.PdfViewerServer.Windows

Styling on 19.4.0.56 works.

If I update to 20.1.0.47 then it does not work. The toolbar buttons, etc. just look like unformatted text.

It seems that  bootstrap5.css is missing.

Edge development tools:

Try to access bootstrap5.css gives a 404

Reverting back to version 19.4.0.56 works and bootstrap5.css is available.

No changes are being made to anything other than change the upgrade/downgrade the NuGet.

These are in _Host.cshtml

    <link rel='nofollow' href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />

    <script src="_content/Syncfusion.Blazor.PdfViewer/scripts/syncfusion-blazor-pdfviewer.min.js" type="text/javascript"></script>

Startup.cs has 

services.AddSyncfusionBlazor(options => { options.IgnoreScriptIsolation = true; });
