I tried this on 

POSTGIS="2.4.4 r16526" PGSQL="100" GEOS="3.6.2-CAPI-1.10.2 4d2925d" PROJ="Rel. 4.9.3, 15 August 2016" GDAL="GDAL 2.2.4, released 2018/03/19" LIBXML="2.7.8" LIBJSON="0.12" LIBPROTOBUF="1.2.1" RASTER PostgreSQL 10.3, compiled by Visual C++ build 1800, 64-bit

and returns true.

I'm dismissing this as a works for me.

Definitely still an issue. I think PostGIS may remove the empty components before passing the geometry over to GEOS.
