No mouse decorator when dragging Event Dispatcher from My Blueprint panel

Currently there is no mouse decorator when dragging event dispatchers out of the My Blueprints panel in the Blueprint editor.

This contradicts the functionality of drag-and-dropping variables, functions, and events. Not a regression.
