'/data remove' does not delete BeamTarget tag in End Crystals, instead 'zeroes' it

Attempting to delete a compound tag does not delete its children, attempting to delete a child merely changes the value to 0.

How to recreate:

1. /summon end_crystal ~ ~ ~
2. /data merge entity @e[type=end_crystal,limit=1,sort=nearest] {BeamTarget:{X:100,Y:100,Z:100}}
3. /data remove entity @e[type=end_crystal,limit=1,sort=nearest] BeamTarget
4. /data get entity @e[type=end_crystal,limit=1,sort=nearest]

Notice the beam still exists, and the NBT still has the BeamTarget tag, with the appropriate unmodified children.

Attempting to remove the children simply 'zeroes' the values:
/data remove entity @e[type=end_crystal,limit=1,sort=nearest] BeamTarget.X

Thus there is no way to remove the BeamTarget tag that I am aware of, aside from deleting the entity.
