Hoglin, Piglin and Zoglin spawn egg problem

^{Update by [Mod] LateLag}
The bug:

Newer spawn eggs such as the Piglins, Hoglins and Zoglins may appear different from their inventory icons when being held or dropped. This can be easily noticed in the Piglin Spawn Egg and both the Hoglin and Zoglin eggs, to a lesser extent.

Notes:
Original description:

The Zoglin spawn egg texture became Hoglin's spawn egg texture and Hoglin spawn egg  texture became Zoglin's spawn egg texture Mojang must fix it..This problem is on Minecraft Pocket Edition.
