[MC-78578] marker Armorstands appear black in blocks

I created an ArmorStand (placed it down) and
execute 2 commands:

tp @e[type=ArmorStand,r=5,c=1] ~ ~-0.5 ~
entitydata @e[type=ArmorStand,r=5,c=1] {Marker:1b}

now there is a marker Armorstand in the ground
and it's black, but if I remove the marker tag with

entitydata @e[type=ArmorStand,r=5,c=1] {Marker:0b}

it's looks normal

therefore the block on the head is also black.

Probably intended, as marker stands' eye level is at its feet.

More "Working by Design" as stated before, see e.g. MC-76592
Use Marker alsways with Invisible.

This issue is present once again in snapshots 15w44b and 15w45a (as far as I know)

Confirmed for 15w51b

@@unknown: This is "Working by Design" , see MC-76592

This is present again in 1.12.1. Invisible is set and the Marker is true. The armorstand becomes dark if it's head is in the ground.

This is present again in 1.12 😞
