When using Minecon 2016 skin pack capes, the cape itself isn't visible in-game and in the preview

• The latest bedrock beta build introduced capes in the custom skin editor;
• However, in the process, it broke all capes present in the Minecon 2016 skin pack;
• When attempting to set a skin with one of those capes from the skin pack, the cape in the preview and in-game is not visible at all.

Steps to reproduce bug:

1. Launch Minecraft Bedrock v1.14.0.3 Beta on a Windows 10 machine;
2. Open the skin editor on the bottom right;
3. Create or modify an existent skin in the skin selection menu;
4. In the skin pack menu of the skin editor, choose one of the Minecon 2016 skin pack's skin. Ensure that the skin is supposed to have a cape attached to it;
5. Notice the issue in both the preview and in-game.
