Steps to reproduce:
Put a cape on any Classic Skin (in the video I tried skinpacks: 1st Birthday Skin pack, Lunar New Year of the Ox)
Restart the game
Expected result:
After starting the game, when the Skin loads, there should be a cape on it.
Reality:
When you start the game and you have a Classic Skin on, the cape disappears, but when you use a Character Creator skin, the cape remains.
This is still a problem for the new 26.42 minecraft update, the capes on classic skins are not appearing until you open the cape section in the dressing room
