PDFViewerServer - Spinner stays shown when zoom is 75%, FitPage, or Automatic

I'm using the EJ2.Blazor.PDFViewerServer version 17.4.44

If I have a pdfviewer control declared and it is inside a container that forces the viewer to use 75%, FitPage, or Automatic then after changing the DocumentPath the spinner does not hide after the document has loaded.

As described I'm loading the document by changing the value of the DocumentPath variable and not by using the PdfViewer.Load event (although it seems to do the same using the event).

Markup -

<EjsPdfViewerServer Height="@strPdfViewerHeight" @ref="@PDFViewer" DocumentPath="@strFileArchivePath" ToolbarSettings="@ToolbarSettings"></EjsPdfViewerServer>

After the document has loaded if you the use the toolbar to change the zoom to 100% or 200% it then shows the document and hides the spinner, if you then change the zoom back to FitPage, Automatic or 75% after the document is shown it then shows a glitched spinner overlayed over the document.

This only seems to happen if the viewer is in a container that is restricting its width, i for example have it in the right column of a 3 column layout.

Interestingly if you are in chrome and you press F12 to show the debug console you can force this behaviour because it squeezes the width of the pdfviewer.

This does not happen in the 17.4.29-beta 

Any help appreciated, i hope you can reproduce the error and suggest a workaround.

Many thanks,
