Marker armor stands go through walls

Resolved
Works As Intended

The bug

Marker armor stands with the Motion tag can be moved through blocks.

How to reproduce

  1. Summon a marker armor stand with the following command:

    /summon armor_stand ~ ~ ~ {Marker:1,Tags:["test"]}

  2. Build a wall east to the armor stand (Not too far away, recommended about 4 blocks away from the armor stand)

  3. Type the command:

    /data merge entity @e[type=armor_stand,tag=test,limit=1] {Motion:[1.0,0.0,0.0]}

    → ❌ The marker armor stand went through the blocks as if they were air and ignored them completely

Most likely intended since it's a Marker armor stand.

...what?
So the fact that it's a marker means it should go through walls?

Marker armor stands have no hitboxes or collision.

Marker armor stands have a hitbox at a size of 0. There is nothing said about collision.

If it's intended, then there is still a bug:

the marker armor stand does not go through a wall until it makes an initial collision

Also, This bug entry is out of date - Apparently the armor stand would flat out go through blocks. (in Minecraft 1.10.2) The bug has changed (in minecraft 1.13) such that it will NOT go through the first block that it hits, but any subsequent motion afterwards will ignore all collisions.
