The bug
When you unleash a mob, the lead will drop even if you do it in creative mode. The lead should not drop if you do it in creative mode. There is absolutely no reason for the lead to drop in creative mode.
How to reproduce:
Be in creative mode
Spawn a mob that can be leashed, such as a pig
Leash it
Unleash it
Observed result: The lead dropped as an item.
Expected result: The lead won't drop as an item.
You will also notice that the hand swing animation does not play, which is a different bug (MCPE-52105).

ys But this doesn't match java and console Edition. In these versions it does not happen. Why should the lead drop in creative mode?

In PS4 Edition, when unleashing an animal, the lead dropped as an item, same as when lead breaks.
It is same on Bedrock Edition.
Java Edition may be different, maybe Mojang will bring Java into parity with Bedrock as Bedrock Edition is now the main game per Microsoft.

For me on xbox one Edition (the old console Edition that is not supported and doesnβt get updates any more) the lead does not drop as an item when I unleash the mob in creative mode. Lead dropping when destroyed for example when you are far away is correct, but it should not drop when you unleash it yourself while being in creative mode.
