The Bug

The visual leash created when leading two or more invisible entities wether attached to the player or a fence connects to the endpoint of other leashes. This can easily be recreated by putting two cows in glass boxes then leading both and splashing them with invisibility.

Steps to Reproduce

• Obtain two leads and summon two cows in front of you.

  /summon minecraft:cow ~1 ~ ~-2.5 {NoAI:1b}
  /summon minecraft:cow ~-1 ~ ~-2.5 {NoAI:1b}
  

• Attach a lead to each of the cows and give both of them the invisibility effect.

  /effect give @e[type=minecraft:cow,sort=nearest,limit=2] minecraft:invisibility 999 0
  

• Look at the leashes carefully.
• Take note as to whether or not leashes from two or more invisible entities connect to one another.

Observed Behavior

Leashes from two or more invisible entities connect to one another.

Expected Behavior

Leashes from two or more invisible entities would not connect to one another.
