From a bug report, if you polymorph into
something, like a killer bee, that causes you to drop your weapon, but the
weapon is a wielded, in-use leash, the leash would be dropped but retain
it's in-use state. However, the leash was tied to you, so it seems it
should remain attached, just unwielded, just as it would if it hadn't been
wielded. I've changed the behavior to do this. I wonder whether one
should be able to wield an in-use leash.
