Comment (by strk):

 Wrong again: `GEOS_CoordSeq_isCCW` can still fail depending on where you
 start walking ( see https://woodie.osgeo.org/repos/30/pipeline/4273/83 and
 detail in
 https://github.com/libgeos/geos/issues/1425#issuecomment-4238347867 )

 New attempt at fixing this problem ALSO on MacOS is dropping the dangling
 components when determining orientation. Experimental branch in that
 direction is in https://gitea.osgeo.org/postgis/postgis/pulls/292
