[MCPE-45318] custom skins loading invisible in 1.11 but loaded fine in 1.10

Since updating Minecraft to 1.11 when I load a custom skin it appears in the skin selection menu as invisible. The same skin would load fine in 1.10. I have tested this on an iPad and an iPhone 6 both running iOS 12.2

Repro steps

have a known working custom skin on device
open skin menu
tap load custom skin
select custom skin on device
select done
