Use Item Stat Corresponds to Left-click, Not Right-click

I was trying to make a scoreboard objective that detects when you use shears, but when I added it and used the shears, it didn't work. I tried shearing both mooshrooms and sheep. Neither worked, and I don't know why. It should work because stat.useitem.359 should detect when shears are used.

Step 1: Add an objective that detects when you use shears (food, shears, bows, potions, and many more also do not work)
(/scoreboard objectives add Shear stat.useItem.359)

Step 2: Set the display to sidebar so you can see if it worked or not.

Step 3: Shear a sheep. (You can also try using the items listed above)

If you followed those steps correctly, you should have not gained any points. It should work, but for some reason, it doesn't detect when you used the shears.
