Enchanted Elytra turns invisible when player is not holding an item.

This bug only occurs in Minecraft Realms.

When a player is wearing an Elytra, the Elytra turns transparent when the player is not holding an item. This affects both enchanted and un-enchanted Elytra's. (See attachments)

The Elytra turns visible again when the player is holding an item in any or both hands.

This does not occur in Singleplayer and Multiplayer; only Realms.
