Nope, this is still an issue. Last run someone opened the chest and I was apparantly too far away to even see the drops, so I got nothing. IMO, this should be fixed, specific to Hamlet defense, as we are at the mercy of anyone in party who is unaware of how this works, and may open the chest prematurely. The drop rate is horrible enough to begin with. Spending close to an hour each run with re-entry cooldown only to have this happen just isn't right.
