misculling actually-visible faces with blockstate culling #2

[Paladynee]

(second case of misculling i encountered, predecessor #341)
(moreculling up to date)

on 1.21.4, with more culling "BlockState Culling" setting turned on, and the "Whimscape 1.20.2-1.21.4_r2" resource pack installed, the north side of any non-full block (slabs, enchantment table, soul sand, trapdoors (ironically lol)) is misculled when all of the following is fulfilled:

• Next block towards North is a trapdoor
• Trapdoor is not of copper type or cousins
• Trapdoor is placed eastwise or westwise
• Trapdoor is open
