Prototype mode: Backspace should delete wire
I would expect the backspace key to remove transitions (in Prototype mode) instead of objects/layers.
Use case: In the Design mode the users adds & removes panels, afterwards he makes the switch from Design to Prototype mode. There his mindset is to create (and remove) transitions. He wants to modify the prototype and add/remove transitions. After selecting a (blue) transition, he presses the backspace key to remove an already existing transition, but as of XD v0.6.1.13 the layer/artboard where the transition originates from disappears.
What the backspace key is in Design mode (to undo one's action = removing an object), I would also expect it to be in Prototype mode (= to remove a transition).

In recent releases of XD, you can now delete wires using the backspace key.
