PdfViewer Handwritten Signature error

Hi,

using PDfViewer when signature panel is open with a click on external button with the following call:

private SfPdfViewer PdfViewer {get;set;}
[...]
this.PdfViewer.OpenSignaturePanel(true);

the signature panel is shown correctly. However when the user click on create to insert its signature, the following error appends and no signature is added to document:

Cannot read properties of undefined (reading 'offsetParent')
TypeError: Cannot read properties of undefined (reading 'offsetParent')
