Firefox ESR 38 has reached it's end-of-life and has been superseded by Firefox ESR 45. The issue is no longer reproducible in Firefox ESR 45, because Fx45 uses a newer ICU release which contains the necessary updates for the Russian time zones (bug 1210165). Therefore resolving the issue as works-for-me.
