I have no idea if this was intentional or a bug. I found this bug while playing MINECRAFT: Bedrock 1.8.0 on Nintendo Switch. I placed an armor stand and placed a helmet on it, but whenever I use the invisibility effect (either using splash potions or commands) on the stand, for some reason the helmet also becomes invisible. When I remove this effect, the helmet appears once again.

NOTE: This bug was found on Version 1.8.0, NOT 1.10.0, but could still be affecting the latest version of Bedrock.
