when the "enable dithering for mobs" is disabled, the mushrooms on the mooshroom cow still are affected by dithering

Steps to reproduce:

1. Settings > accessibility > turn off “enable dithering for mobs”
   

Enter a world and spawn in a mooshroom, and go close to it
Observed Results:

The mushrooms on the mooshrooms are affected by dithering still, despite enable dithering for mobs

Expected results:
The mushrooms on the mooshrooms are not affected by dithering, like the body of the mooshroom when enable dithering for mobs is turned off



The Mushroom Cow's mushrooms have a dotted effect even when the option is disabled, and the lighting on the Mushroom Cow's mushrooms also has an error.
