marker armor stands fall through the ground

When summoning a marker armorstand with non-null speed, it will ignore the firsts blocks for collision, and fall through the ground

How to reproduce:

/summon armor_stand ~ ~ ~ {Marker:1b,Motion:[2.0,1.0,2.0]}

Do this in front of a mountain and see the armorstand ignoring the first blocks of the mountain and falling through the ground

This is very annoying for any custom projectile in datapacks
