Faces of some blocks are not at all culled when said face is hidden by a solid, opaque block

NOTE: this ticket should probably be split in future for simplicity.

Cases which are already split:

• Dragon eggs (MC-199238)
• Fence gate (MC-238734)
• Beacon (MC-239142)
• Torch (MC-275792)

The bug

Certain faces of blocks are still rendered even in conditions which would make them absolutely impossible to see outside of spectator mode.

This ticket only lists blocks which use the standard block rendering method and not blocks such as chests which render differently in a manner similar to entities.

Affects the following blocks, as seen in Spectator mode through an opaque solid block:

Bottom faces:

• Brewing stands
• Iron bars
• Glass panes (fix provided in MC-122927)
• Four turtle eggs (fix provided in MC-135986)
• Chorus flowers

Side faces:

• Anvils
• Bell (attachment:floor)
• Chorus flowers

Top faces:

• Anvil
• Glass panes
• Iron bars
• Chorus flowers
