When creating a formula in Libreoffice Writer which takes the form "p(x|y)", the pipe symbol "|" gets converted to the logical or symbol "v".
When I replace "|" with "divides", I can see the "|" symbol correctly now in the formula. However, when I save the result, close and open the document again, the logical or symbol "v" is back.
Confirmed with current master/7.0.0 alpha1+

Roundtrip ODF retains the sm 'divides' syntax and renders formula with a "|" symbol.
but on roundtrip with OOXML, 'divides' gets mishandled as "|" and parses it as the "V" logical OR.
