Bottom Monster Spawner Texture Overlapping

So while watching the monster spawner mechanic I’ve encountered some weird texture overlapping.

When u place any block not counting shulkers, glass, shelfs, cauldrons, scaffolding, beacons etc.

the bottom texture of monster spawner gets overlapped by the block underneath.

This bug seems really weird, it doesn’t work for some blocks that are counted as full but other

blocks that are counted as full are affected with this overlapping.
