Summary
I was Testing out banners and i made a wolf banner then to my surprise when i placed down the banner it looked nothing like it looked in my hotbar Some of the layers in the banner went transparent aswell But when i reloaded the world after i placed it , it has appeared like it was supposed to. Please fix i really don't want to reload my world each time i place a banner.

What I Expected to happen..
1) I Make the wolf banner.
2) I get it in my hotbar.
3) I place it down and it appears normally

What Actually Happened:
1) I made the banner.
2) i got it in my hotbar.
3) I place it down and some of the layers of the banner appear to be transparent.
4) restart the world for it to appear correctly after it has been placed already.

Steps to reproduce:
1) Create a banner with quite a few layers.
2) Get it in your hotbar.
3) Place it down.
