KeyboardDragListener doesn't interrupt on blur

[jessegreenberg]

I noticed that the KeyboardDragListener doesn't interrupt itself on blur which is surprising to me. I am using one without a GrabDragInteraction in quadrilateral and tabbing away from the Node while movement keys are down result in the pressed keys staying in the keyState array. This isn't a problem for GrabDragInteraction because of these lines

Fixed in the above commit, @zepumph is this change OK with you?

I can't think of any reason that would be bad. Thanks!

Similar to this, I just saw that interrupt doesn't call end. @jessegreenberg please let me know if that seems buggy to have. It seems important to keep this implementation aligned with DragListener (from interrupt/release).

Ran into this over in phetsims/my-solar-system#86

Spot check from @jessegreenberg, I basically copied the idea from

scenery/js/listeners/PressListener.ts

Lines 547 to 551 in 80e2985

	// it is possible we are interrupting a click with a pointer press, in which case
	// we are listening to the Pointer listener - do a full release in this case
	if ( this._listeningToPointer ) {
	this.release();
	}

This change makes sense, thank you! Looking for other cases like phetsims/friction#342, but I didn't see anything else.

Closing.
