Bug
Whenever I summon an end crystal using BeamTarget NBT, the beam does not render at all

Steps to Reproduce

• Load a creative world in any of the listed versions (also affects 1.20.5, 1.20.6, and 1.21.0; the site doesn't let me pick anything but 1.21.1 for some reason)
• Run /summon end_crystal ~ ~ ~ {BeamTarget:{X:0,Y:0,Z:0}}
  (coordinates don't matter)
• Alternatively, run /data merge entity @e[type=end_crystal,limit=1] {BeamTarget:
  Unknown macro: {X}

  }

When summoning or modifying an end crystal with a beam attached, the crystal renders the beam at the designated coordinates

Observed Behavior
When summoning or modifying an end crystal, the beam does not render at all (single and multiplayer; might be client-side) nor does it show up in /data get
