This has been an issue for quite awhile now and does still seem to be the case. You can no longer 'run' through a Item-Holo and have the pickupHandler fire. Jumping over it or 'falling' through it seems to be the only way that works now.

Sorry for not answering on this. This should have been fixed somewhen, I will now close the issue since it's old. If not, please answer and I will reopen it.
