Prior to 1.19, paintings could be placed behind signs but since updating, it won't work. Also please don't mark this as "Works As Intended" or "Invalid" as it is a genuine issue that has arised as part of the 1.19 update. Prior to 1.19, paintings could be placed behind signs by right clicking the exposed part of the block that the sign is on. Since updating, trying to place a painting behind a sign does nothing except produce a clunky grinding sound
Steps to reproduce:
1. Place a sign on a side of a block.
2. Try to place a painting on the same block, behind the sign.
Prior to 1.19, paintings could be placed behind signs by right clicking the exposed part of the block the sign is placed on. Since updating, this ability no longer works
