I was using a world to practice with a wind burst mace when I noticed that the particles that appear when you use the smash attack (in the attached video, they're grass block particles) didn't always appear when I hit a specific warden. Notes: the wardens have NoAI enabled, and this did not consistently happen. Sometimes the particles were there, sometimes they weren't. This always happened on the 5th warden in line when it did occur, however.

The link to the video is here: https://1drv.ms/u/s!AtbAdFV0CBFBgyayISUyB0tBh4F9?e=Uh5aN5
Steps to reproduce:

• Create a world (I used the default superflat preset with 100 layers of dirt)
• Create a line of a mob (I used wardens, I'm not sure if it works with other mobs
• Give yourself a mace (Mine has the unbreakable tag)
• Enchant said mace with density 5 and wind burst 3
• Use the smash attacks to go down the line, hitting all the mobs

Expected result:
All of the smash attacks would cause the block particles to be sent out

Result seen:
A certain attack, on occasion, would not send out the particles
