Item renders in front of stack size number when being quick moved. This issue is introduced due to a new quick move animation in one of the 1.21.0 preview versions (I don't know exactly which), and thus does not happen in 1.20.73.

Steps to Reproduce:

1. Open an inventory.
2. Quick move some stackable items.
3. Take a look closely at the item while the quick move animation plays.

Observed Results:
Item renders in front of stack size number while the quick move animation plays.

Expected Results:
Item would always render behind the stack size number.
