I have tried to mine the new warped nether wart block and nether wart block with all the hoe's in the game. First i tried to mine with a hand to check how much time it takes to mine (its slow). Then i tried to the same thing but with a diamond hoe. It gives the same speed as mining with a hand. I have a visual proof the bug and i have compared the mining with a hand and a hoe side to side.
How To Reproduce:
Step 1:- Take a diamond or netherite hoe.
Step 2:- Mine it.
Should be fast.
Hoping this information is helpful to fix this hug.
