The hopper and barrel on the upper floor of the `chamber_8` trial chamber structure never generate

The Bug:

The hopper and barrel on the upper floor of the chamber_8 trial chamber structure never generate.

Trial chambers place hoppers and barrels through jigsaw blocks that use the minecraft:trial_chambers/decor/disposal target pool, including the one on the lower floor of chamber_8. However, the one on the upper floor uses the minecraft:trial_chambers/decor target pool instead, which has no pieces that can connect to it, therefore introducing an inconsistency.

Steps to Reproduce:

1. Place the chamber_8 trial chamber structure and teleport to the said jigsaw block by using the commands provided below.

   /place template minecraft:trial_chambers/chamber/chamber_8 ~1 ~ ~1

   /tp @s ~15 ~12 ~13

2. Open the jigsaw block that’s in between the floor and the wall.

3. Set “Levels” to 1 and then click the “Generate” button.

4. Observe if a hopper and barrel generate.

Observed Behavior:

No hopper and barrel generates.

Expected Behavior:

A hopper and barrel would generate.
