Honey blocks should prevent adjacent shulkers from teleporting when pushed by a piston

Current behavior: When a shulker is attached to a block which is pushed by a piston, the shulker teleports to another randomly chosen block.

Given that a major feature of the new honey blocks (19w41a snapshot) is that they pull entities including mobs with them, it would be fitting if a shulker would NOT teleport when the block it is attached to is pushed by a piston, if that shulker is ALSO adjacent to a honey block which is being pushed by the same piston. See included image for an example of a shulker that should NOT teleport when pushed (it currently does).
