[MC-45762] Paintings placing incorrectly

When I started my world, all my item frames and paintings flew off the walls. I replaced them, but paintings that are two blocks wide don't align properly to the blocks.

What I expected to happen:
The paintings would align to the sides of the blocks.

What actually happened:
The paintings placed strangely.

Steps to reproduce:
1. Place a painting that is two blocks wide on a block that has two blocks next to it, on either side.
