A bibliography with an empty first paragraph

The attachment DOCX has one citation field, and one bibliography field. The bibliography has an empty leading paragraph inside (that is how it was in an original customer document), and then two entries. It is imported into LibreOffice with an empty paragraph inside the bibliography field, but both bibliography entries are imported as simple paragraphs after (outside) the bibliography field. Note that Word 2016 imports them: the empty paragraph and the following entries - inside the field.

The problem is that the bibliography field and its first entry have this XML definition:

>                ...
>                <w:sdt>
>                    ...
>                    <w:sdtContent>
>                        <w:p>
>                            ...
>                            <w:r>
>                                <w:fldChar w:fldCharType="begin"/>
>                            </w:r>
>                            <w:r>
>                                <w:instrText xml:space="preserve"> BIBLIOGRAPHY </w:instrText>
>                            </w:r>
>                            <w:r>
>                                <w:fldChar w:fldCharType="separate"/>
>                            </w:r>
>                        </w:p>
>                        <w:p>
>                            ...
>                            <w:r>
>                                ...
>                                <w:t xml:space="preserve">Christie, A. (1922). </w:t>
>                            </w:r>
>                            ...

while usually it looks like

>                ...
>                <w:sdt>
>                    ...
>                    <w:sdtContent>
>                        <w:p>
>                            ...
>                            <w:r>
>                                <w:fldChar w:fldCharType="begin"/>
>                            </w:r>
>                            <w:r>
>                                <w:instrText xml:space="preserve"> BIBLIOGRAPHY </w:instrText>
>                            </w:r>
>                            <w:r>
>                                <w:fldChar w:fldCharType="separate"/>
>                            </w:r>
>                            <w:r>
>                                ...
>                                <w:t xml:space="preserve">Christie, A. (1922). </w:t>
>                            </w:r>
>                            ...

Note that in the "usual" XML, the run with <w:fldChar w:fldCharType="separate"/> element is immediately followed by another run with the first entry, which therefore is inside the paragraph entry defining the bibliography field; while in problematic XML, the run with <w:fldChar w:fldCharType="separate"/> element is the last run of the paragraph defining bibliography field, and the first entry is in the following paragraph.

The 4.3 is the first to import bibliography fields as fields, so implementation error.
