Missing water in trapdoors in taiga villages, causing mobs to become trapped in them

The Bug

Trapdoor decorations in taiga_decoration_1, taiga_butcher_shop_1, taiga_masons_house_1, taiga_temple_1 and taiga_tannery_1 do not have water inside them. MC-130584 was fixed and therefore adding water should be no problem.

Trapdoors in taiga_decoration_1 had water until 19w02a.

MC-50556 and MC-199420 are set to WAI, but it wasn't officially said that this is intentionally empty.

To Reproduce

1. Execute the following command, replacing (structure_name) with the name of the affected structures:

   /setblock ~ ~ ~ structure_block{mode:"LOAD", name:"minecraft:village/taiga/houses/(structure_name)",showboundingbox:1}
   

   For example:

   /setblock ~ ~ ~ structure_block\{mode:"LOAD", name:"minecraft:village/taiga/houses/taiga_tannery_1",showboundingbox:1}

2. Open the structure block GUI and click on "Load" twice.
3. Observe that the trapdoor decorations are missing water.

Expected Result

Trapdoors decorations in taiga villages should have water inside them.
