I'm still unsure how not being able to drop while looting with a pet is intended behaviour. [MENTION=247]Combattente[/MENTION]; do you know why it's intended?

Well, let's say this. The client-server interaction doesn't seem to be accepting some types of simultaneous operations. For example, I think it is not possible to attack AND drop an item at the same exact time. For the same reason, it's not possible to drop while looting with a pet, and perform several other simultaneous operations. Some of them are allowed through integrative systems such as pet looting while attacking, but that's because they purposely added a function for that.
