[MC-310855] Cushions break when sharing block space with certain solid blocks

Summary:
Cushions break when certain solid blocks are placed inside their block space. This violates parity with Bedrock Edition.
The affected blocks are:

Beacon
Glass
TNT
Shulker Box
Ice
Leaves

Steps to reproduce:

Place a cushion on a solid block.
Place any block from the list above into the exact same block space as the cushion.
Wait a few seconds.

Observed results:
The cushion breaks immediately and drops as an item.

Expected results:
The cushion should not break and should remain inside the placed block, matching the behavior in Bedrock Edition.

Thank you for your report!
After consideration, the issue is being closed as Won't Fix.

Please note that this is not the same as Working as Intended, as this bug report correctly describes behavior in the game that might not be the intended or desirable behavior, but it will not be fixed right now. Sometimes, this is because the issue reported is minor and/or impossible to change without large architectural changes to the code base.

Note: this behavior might change for some blocks, but will not be fully fixed since it is tied to systems with pre-existing parity differences. Bringing those systems into parity is a pre-existing issue tracked elsewhere.
