Cobwebs in corners sometimes have incorrect shading/ambient occlusion

Cobwebs have darker shading on one side when placed on corners in caves. Every other cross model in the game has 0 ambient occlusion.

Since cobwebs are also affected by MCPE-190242, this visual issue cannot be resolved with just a resource pack.

To Reproduce

1. Create a new world in Creative Mode with Cheats using seed “cobweb”

2. Run this command: “/tp @s -48.22 58.37 401.30 facing -48.51 57.8 404.00“

3. Run this second command: “/fill -49 57 404 -49 60 404 web”

4. Observe the unnatural cobweb shading.

Expected Result

Cobwebs have no ambient occlusion, like all other cross models.

Observed Result

Cobwebs sometimes have ambient occlusion.
