Elytra can't be set to Chestplate Slot w/ Replaceitem, but can be set to head slot

Seems like it can be replaced onto the head slot, but not the chest, leg, or foot slot. Seems like the slot is just messed up. Easy fix hopefully!

Ok, this definitely is a bug, but a friend told me that you can at least use the tag {Inventory:[{id:minecraft:elytra,Slot:102]} should work when testing for it (/testfor, /scoreboard...)
But that still doesn't solve the problem for replace item...

the problem is that it doesn't allow the elytra in that slot as it doesn't recognise it as a valid "chestplate" item, it works fine with any chestplate. This is probably to prevent any non-chestplate items to get in this slot and render incorrectly or crash the game.

probably the fix is as easy as adding "minecraft:elytra" to the whitelist for this slot.

Mods, please investigate this issue.

I agree Spake Miner.
