Redundant check for Wolves in source code

Not sure if it’s 100% a bug, but surely a mistake in the code. Class net.minecraft.world.entity.animal.wolf.Wolf, line 366/367 on tick()method. The IF condition does this redundant check:

else if ((this.isWet || this.isShaking) && 
      this.isShaking) {

Checking for “isWet” doesn’t make any sense at all; because IF “isShaking==true” it will pass anyway.

This has been there since wolves were added in Beta 1.4, but now that the client comes without obfuscation, it is 100% certain that this is a mistake in the code and not the decompiler going crazy.

Of course, this doesn’t impact gameplay in any way. But it’s weird.
