Comment (by strk):

 It's hard to tell who's right and who's wrong between GEOS-3.8 and
 GEOS-3.12 because the error could also be in a false negative validity
 detection too. Comparing logs when run against 3.8 and 3.12:

 {{{
  3.8: [topo/lwgeom_topo.c:_lwt_CheckEdgeCrossing:700] Edge 4 relate
 pattern is FF1F00102
 3.12: [topo/lwgeom_topo.c:_lwt_CheckEdgeCrossing:700] Edge 4 relate
 pattern is F01F001F2
 }}}
