Make EventOnDrop ignore certain widgets, and bubble past them

I have setup drag & drop for my HUD widgets. Everything works great, until I drop one of my widgets onto another, then that starts to cause problems. I am looking for way to tell my OnDrop event to bubble down to other widgets, like my main HUD widget and just ignore other draggable widgets, but am not seeing a way to do this. Leaving the return value unchecked on the OnDrop event doesn’t seem to help either. I know how to check what the current widget that I’ve dropped onto is, but am unaware of how to bubble the event down to my hud so that the widget can be placed.

After some looking around, the OnDrop event cancels the drag & drop regardless of whether or not it is handled, just thought I’d mention it.
