turf.union(turf.featureCollection([a,b,c])) // problematic
turf.union(turf.featureCollection([c,a,b])) // ok
the first union gives:
TypeError: null is not an object (evaluating 'this.rings.length')

upgrade to @turf/turf 7.2.0 seem to be ok, but why?
ALSO, upgrade to 7.2.0 cause problem like #2909 that also bugs me. NOT directly upgrade to the new version right now.
