Severe lag on /clear command when items are in the inventory's 2x2 crafting grid

/clear command has severe performance drops (increased mspt) when there are items in the player inventory's 2x2 crafting grid. Following the reproduction steps below results in roughly an 11x increase in mspt.

For counting items, /execute if items can be used as a temporary workaround.

Steps to Reproduce:

1. Create a new void superflat world.

2. Set up a repeating command block to count items 1024 times per tick using /clear.
   (For example, summon at least 4 entities into the world and put the following command into the command block):

   /execute rotated as @e[limit=4] rotated as @e[limit=4] rotated as @e[limit=4] rotated as @e[limit=4] rotated as @e[limit=4] run clear @a * 0

3. Change the gamemode to survival.

4. Place an oak_log item into the player inventory's 2x2 crafting grid, and observe the sharp increase in lag (with the F3+2 graph).
