None of the wall sign block display renders correctly.

None of the wall sign block display renders correctly. All wall signs are rendered as their regular variants. Moreover, the properties: "waterlogged" and "facing" have no effect and do not render correctly.

Steps to reproduce the issue:
/summon block_display ~ ~ ~ {block_state:{Name:"minecraft:oak_wall_sign",Properties:{waterlogged:"true"}}}

Expected result:
A Block Display should be summoned with the render of a wall sign that is waterlogged.

Actual result:
A Block Display is summoned with the render of a regular sign that is not waterlogged.
