Creeper texture bugged while using classic texture pack

When you log into bedrock minecraft with the classic minecraft texture pack, every creeper is displayed as a charged one, and the animation isn't moving, this is only a visual bug.

Expected result
Classic texture pack creeper would have the normal classic texture

Actual result

Classic texture pack creeper is displayed as a charged creeper no matter if it is charged or not, the charged animation also doesn’t move.

How to reproduce

Log into bedrock minecraft with the classic texture pack enabled and spawn a creeper.

This is a small visual bug, but still mildly irritating during thunderstorms.
