When you dye sheep to any of the colours and shear them, their "naked" skin still shows patches of wool that is white instead of their true colour.

Because of this it is impossible to (ever) tell dyed sheep apart when they've been sheared.

It's always been like this, but it shouldn't. If you use dye on a sheep, it should not leave patches of white behind on its skin. Especially if the sheep was never generated as white to begin with.

I really thought this was fixed in 1.12, got my hopes up. I'm convinced I had read it in some changelog, but now I can't find it anywhere. I found it in Bedrock documentation.
