It's related to MC-13949 but with this command:
/execute as @e[type=!player] run data modify entity @s Leash set value {}
Then the lead drops and i have no way to prevent that (MC-75494 might be enough....)
Can confirm that this is an issue in 20w51a. I've attached a video demonstrating the problem.
Fixed in 23w06a.
