Drag And Drop Widget on over other widget

Hey, everyone!
I have Drag and Drop operation for moving widgets, if I try to move widget A and drop it on selfHitTestInvisible border part of widget B it will be OK, but when I’m dropping on parts that visible for hits like buttons and slots, widget A is not spawning in new location so it’s disappered. How can I say to my moveable widget A to ignore everything and hit on drop only HUD Canvas OR that would be great also check if something was wrong and return moveable widget A in origin?
