Whenever you leash an animal and unleash it right after, the lead doesn't get dropped. This isn't the case with the fireproof lead, everything is fine there. I really hate this "feature" and can you show me how to fix it.

Tested through my 100 mods modpack just to find this issue from here, I really want to change it to be vanilla behaviour.
