(Marker) Armor stands create bubbles in water

Armor stands with Marker set to true create bubbles underwater, which breaks immersion, as those marker-armor stands are only usable/producible in Creative and valuable mapmaker tools. Armor stands get this behaviour as they are part of EntityLiving. As soon as the armor stand hitbox/eye height is underneath water, bubbles appear.

That's why an armor stand with Marker false does not create bubbles, as long as it's solely with its "feet" in water, but not with its "head" or rather at its eye height:

As soon as a Marker-false armor stand is underwater at eye height, it'll also create bubbles like the Marker-true armor stand:

As the Marker true armor stand got its tiny hitbox only at its "feet", bubbles appear in any case, when standing in water.

An easy way to solve this without ugly special cases could be to just let

canBreatheUnderwater()

return true for armor stands.
