Description

Following code reproduces the bug. Haven't tested if it persists on Django 2.2.

from django.contrib.gis.geos import GEOSGeometry

linestring = GEOSGeometry('LINESTRING(0 1, 1 2)', srid=4326)
assert linestring.srid == 4326
linestring.reverse()
assert linestring.srid == 4326, 'SRID data is lost!'
