Item stacks can still clip into the block below when hovering on the ground

According to the 25w07a changelog:

Item entity

• When on ground, model size is now taken into account when determining hovering motion

  • That means that models should never clip into the block below, no matter what size they are

However, when the item entity on the ground renders as an item stack, it’s still possible for the model rendered as a cluster of items to clip into the block below. This is barely noticeable on item stacks composed of some items such as dried kelp or sniffer eggs, but can clearly more visible on item stacks composed of blocks or skulls.

How to reproduce:

1. Get a stack of items composed of blocks.

2. Throw the entire stack to the ground.

3. Notice whether or not the item cluster model clips into the ground.

Expected result:

The item stack would hover on the ground without clipping into the block below.

Observed result:

The item cluster can clip into the ground.
