Complex fields are not always closed correctly

[tripodsan]

see http://officeopenxml.com/WPfields.php
the complex fields should be enclosed with a <w:fldChar> element with an attribute fldCharType value of begin and
ended with one with the value of end.

I have a document with a HYPERLINK field, where the end is wrapped in a <w:del> element (don't know how the author managed to do this :-) :

            <w:r w:rsidR="603DAB17">
                <w:fldChar w:fldCharType="begin"/>
            </w:r>
            <w:r w:rsidR="603DAB17">
                <w:instrText xml:space="preserve">HYPERLINK "https://rewards.adobe.com/" </w:instrText>
            </w:r>
            <w:r w:rsidR="00000000">
                <w:fldChar w:fldCharType="separate"/>
            </w:r>
            <w:del w:id="0" w:author="John Doe" w:date="2022-07-21T00:44:00Z">
                <w:r w:rsidR="603DAB17">
                    <w:fldChar w:fldCharType="end"/>
                </w:r>
            </w:del>

In this case, all following paragraphs are wrapped with a hyperlink. I suspect that the <w:fldChar w:fldCharType="end"/> is not detected inside the <w:del> element.

I will try to create a PR with a test soon.
