Elytra display error issue

This is a bug that gets it for nothing

Did you know elytra when you've been to the end city?

My friend and I found a bug while surviving

When we all put on our elytra, we all put on our own capes

The cloak on the elytra is not displayed properly

Even the cloak I had, which my friend didn't, would appear on his elytra

I hope you guys can fix this bug soon
