Description:
I created a Docx file that contains a field with a specific formatting style (Formatvorlage4).
When I open the Docx file with LibreOffice, the formatting of the SDT fields appears incorrect.

Please check the file in attachment.
The field should have the Formatvorlage4 style, but it doesn't appear in the preview.
But in Microsoft Word, I can see the correct formatting (Formatvorlage4).

This is the SDT block:

      <w:sdt>
        <w:sdtPr>
          <w:rPr>
            <w:rStyle w:val="Formatvorlage4" />
            <w:rFonts w:ascii="Arial" w:hAnsi="Arial" w:cs="Arial" />
          </w:rPr>
          <w:alias w:val="Author" />
          <w:tag w:val="" />
          <w:id w:val="519431896" />
          <w:placeholder>
            <w:docPart w:val="477E5E5C83E2482C8987F073F30706BF" />
          </w:placeholder>
          <w:dataBinding
            w:prefixMappings="xmlns:ns0='http://purl.org/dc/elements/1.1/' xmlns:ns1='http://schemas.openxmlformats.org/package/2006/metadata/core-properties' "
            w:xpath="/ns1:coreProperties[1]/ns0:creator[1]"
            w:storeItemID="{6C3C8BC8-F283-45AE-878A-BAB7291924A1}" />
          <w15:color w:val="FF00FF" />
          <w:text />
        </w:sdtPr>
        <w:sdtEndPr>
          <w:rPr>
            <w:rStyle w:val="Formatvorlage4" />
          </w:rPr>
        </w:sdtEndPr>
        <w:sdtContent>
          <w:r w:rsidRPr="00545C0B">
            <w:rPr>
              <w:rStyle w:val="Formatvorlage4" />
              <w:rFonts w:ascii="Arial" w:hAnsi="Arial" w:cs="Arial" />
            </w:rPr>
            <w:t>Steinhofer, Melanie</w:t>
          </w:r>
        </w:sdtContent>
      </w:sdt>

Despite having the Formatvorlage4 rStyle in the run properties (rPr), it does not display correctly in the preview!

Steps to Reproduce:
1. Opening the attached Word Document

Actual Results:
"Steinhofer, Melanie" is displayed in normal style

Expected Results:
"Steinhofer, Melanie" is displayed in Formatvorlage4 style


Reproducible: Always


User Profile Reset: No

Additional Info:
The software should display the field with the correct formatting style, which in this example is Formatvorlage4.
