That would be the idea of the grab-bag, to just save some of those
settings and write them back to docx, without understanding them.

It was added in core.git commit 9992338fbbf46bf381501df6c7763bf117d2ee25
for tdf#79315. If you think the testcase is poor, it's possible to
rework it, just please manually test the original bugreport after your
changes (so the testcase still represents the original problem).

Interestingly reading the word/document.xml of that test document, it
does not look like it was hand-edited after saving in Word.

If you find a poor test, then reworking the test document to better
represent the original problem is a better solution. Adding tolerance
sounds a bit hacky. :-)
