I added carpets to all the 2-block-high areas where I did not want Iron Golems spawning, and that seems to prevent them spawning there. I do not know if it is because it reduces the height or if Iron Golems are being prevented from spawning on carpet, but it seems to be a workaround until the bug is fixed.
