Cannot expand "Pipe Boxes A" object in Desert Object Set

[opsodps]

Dario mentioned this on the Discord, posting it here too because I find it interesting.

The "Pipe Boxes A" object is placeable in Foundry as it appears on the left. However, in the vanilla game, the object appears in levels, such as World 2-1, where it's extended for double the length horizontally (as seen on the right), implying the object is resizeable, but it cannot be resized via Foundry.
