While trying to make full UI postprocess with Retainer Box I stumbled upon a bug. When draggable widget(OnMouseButtonDown + DetectDragIfPressed + OnDragDetected) is wrapped with Retainer Box I’m not getting OnDragDetected event.

Hi dxOne,

I was able to reproduce this on my end and have entered a bug report, UE-30363 to be assessed by the development staff.
