PdfProcessing: Newly created SignatureDataProperties object misses Contents initialization
Sign a random pdf document with the following code. If UseSignatureProperties=1, the produced PDF document will be corrupted and Adobe displays an error message when opening the file: 
        Dim signProp As New SignatureDataProperties
        signProp.ContactInfo = strContactInfo
        signProp.Name = strSignersName
        signProp.Reason = strReason
        signProp.Location = strLocation
        signProp.TimeOfSigning = DateTime.Now

        Dim signatureName As String = "EsignSignature"

        Dim signatureField1 As SignatureField = New SignatureField(signatureName)
        UseSignatureProperties = 1

        If UseSignatureProperties = 1 Then
            Dim sign1 = New Signature(certificate)
            signatureField1.Signature = sign1
            signatureField1.Signature.Properties = signProp 'THIS WOULD FAIL
        Else
            signatureField1.Signature = New Signature(certificate)
            signatureField1.Signature.Properties.ContactInfo = strContactInfo
            signatureField1.Signature.Properties.Location = strLocation
            signatureField1.Signature.Properties.Name = strSignersName
            signatureField1.Signature.Properties.Reason = strReason
            signatureField1.Signature.Properties.TimeOfSigning = DateTime.Now  'THIS WORKS
        End If

WordsProcessing: PdfFormatProvider: StackOverflowException is thrown during PDF export of a document with a Header/Footer containing a page break

StackOverflowException is thrown during PDF export of a document with a Header/Footer containing a page break.

Workaround: Remove page break from all header/footer paragraphs, or from a specific paragraph.

Header defaultHeader = section.Headers.Default;

if (defaultHeader != null)
{
    foreach (var item in defaultHeader.Blocks)
    {
        if (item is Paragraph paragraph)
        {
            paragraph.PageBreakBefore = false;
        }
    }

WordsProcessing: Add support for horizontal line
Add support for horizontal lines in documents.

In DOCX, such lines are defined using the legacy VML definitions:
<w:pict w14:anchorId="324D5836">
  <v:rect id="_x0000_i1025" style="width:0;height:1.5pt" o:hralign="center" o:hrstd="t" o:hr="t" fillcolor="#a0a0a0" stroked="f"/>
</w:pict>
The definitions above and the <hr/> HTML tag are currently not supported and skipped on import, leading to missing horizontal lines in the document.
