/setblock cannot place walls with connection bits

/setblock cannot place walls with variants/metadata

How to reproduce: type /setblock into a Minecraft world, put ~~~ afterwards, and type in a random wall like brick_wall. Then type “[“, and press tab and up/down arrow a few times until the command is filled in, and press enter. The wall will always be a default wall, but for a split second you can see what it would normally look like.
