Strange Glow Effect visual glitch on Iron Golems on their first Damage Skin Change

While I was playing in the  Minecraft Snapshot 20w49a, I discovered that Iron Golems had a visual glitch when hit with a spectral arrow, with a crossbow or bow, when they were on their first skin change due to damage. On their normal skin, and their second skin change, the glow effects were normal and just went around its outline. But on the second on, it acted as if there was holes in it's body around the cracks in its skin. I don't know if this is supposed to be like this, so I reported it. If this is in game, please respond to me, because I think that's kind of cool but just wished it worked with the second skin change too. Thanks.
