Y Sort - In `SicilianHouseInside`, fix issue of Y Sorting not working w/ `Couch` and `Player`

[SimoneRizzuto]

This issue needs to be isolated. Attempt to find if this is a problem with the whole scene, with the couch, or with the player.

• Try remaking the scene from scratch.
• Try couch with other nodes.
• Try player with other nodes.
