When placing items with a custom BlockStateTag NBT tag, certain block states do not take effect. Examples I have found so far include:

• Creating campfires which are unlit by default (Ex: /give @p minecraft:campfire{BlockStateTag:{lit:false}} )
• End Portal Frames with eyes already inserted (Ex: /give @p minecraft:end_portal_frame{BlockStateTag:{eye:true}} )
• All tested blocks which feature the "waterlogged" tag (Ex: /give @p minecraft:oak_fence{BlockStateTag:{waterlogged:true}} )

This does not seem to be an issue with the blocks themselves, as some block states are still applied (Ex: Campfires can be summoned facing a certain direction, but not waterlogged or extinguished.)
