[parity] Multiple item frames cannot share the same block space

Steps to reproduce the issue:

1. Place (regular*) item frame on the top side of a block

2. Try to place another (glow*) item frame next to the first one on a block so that second item frame shares the same block space with the first one

*item frame type doesn’t matter, just using different ones in the attachments to make the order clearer

Expected result: You are able to place the second item frame on the block space as the first one, like on Java
Actual result: You are not able to place the second item frame, parity issue

This parity issue affects everyday gameplay negatively like storage systems, and detailing of small interiors. Fixing this issue would also make map rooms able to use more creative layouts like having a map span across multiple walls without gaps.
