When walking up to a sheep with the shears tool in your hand and right-clicking a sheep, the wool on the sheep does not disappear to indicate that it has been shaved.

Expected result:

The wool on the sheep would disappear for a short period of time after being right-clicked on with the shears tool and then later reappear with new wool on its body.

Actual result:

When right-clicking a sheep with the shears tool, the wool on its body does not disappear.

How to reproduce:

1. Create a world in 1.14 and save it, then enter beta 1.15.0.51 and then load into the world.
2. Obtain the shears tool, find a sheep, and right-click on the sheep.

Note:

Everything else works fine with the sheep, from gaining wool after right-clicking on it to waiting a period of time before being able to do so again, the only problem is what I described.
