Crawl parity issue

Summary:

In Minecraft Java version, it is possible for the player to pass under a slab, giving a total of 0.5 blocks high, as long as there are layers of snow forming an entire block below the player, Something not possible in Bedrock Edition

Steps to Reproduce:

1. Launch Minecraft Java and Bedrock Edition

2. Create a world with "experimental short crouch" enabled 

3. Make a structure with layers of snow forming a block on the ground and place a slab on top of a block

4. Use a Trapdoor to crawl and try to pass under the slab 

Observed Results:

Unlike the Java edition of Minecraft, the player will not sink into the snow while crawling on the snow, making the character unable to go under the slab

Expected Results:

On snow-like blocks, the player should sink slightly and be able to pass under slabs.

Screenshots/Video Attached: Yes

Notes: So far, I've tested it with soul soil, soul sand, honey block, slime block, and layers of snow forming a block. It only worked with soul sand. In java edition it works with soul sand and snow layers
