This is the problem here.
PP (and Word) puts an embedded xlsx into the document which we do not change,
even if the user changes the data table of the chart.
Such changes are saved to chartN.xml, but not to the grabbagged xlsx.
Once the user opens the LO-saved file in PP/Word and tries to edit its data,
they get the grabbagged pre-LO data and at this point any changes made in LO
are lost because MSO actualizes the data in chartN.xml from the embedded xlsx.
I'd not say this is NAB, rather that this is a quite difficult bug.</pre>
