Invisible Skin [Intentional Exploit]

IF Theres a duplicate, please add this info in the normal one, I at least didnt find any duplicates though

~~ This is a GLITCH, Which means people are intentionally triggering to abuse of it, And the Non-Intentional Bug you're looking for is MCPE-51158 ~~

How to Reproduce:
1- Download this specific skin [DROPBOX]
2- Apply it to yourself
3- Done!
[NOTE: If any dev wants to test this for a future version and the skin is just white, simply continue it like this:
2- Apply it to youself
3- Apply steve or alex
4- Apply custom skin
5- Apply steve or alex
6- Apply custom skin ]

As you can see, the process is actually way easier than before you guys "Fixed" it.

Examples in the attachments.

This may not seem like a problem in a singleplayer world, But in servers [Including Mineplex] The armor and shadow dont render too!
