Problematic behaviour: if some documents have multi-valued fields, since we decided to use a return to line character for the multi-valued property value, it breaks the csv format and after the sort we have too many lines
Reproduction:
on nightly set up dc:subjects metadata value on one file of a given folder, setting at least two values.
Go on the parent folder make sure there is a couple of docs at least including the one you just edited and try the csv export feature.
==>You will notice that the exported file is messed up.
Note: at least on Mac OS / Excel 16.9
