Path.onMouseDown changes behavior of Path.onMouseUp

[Octember]

Check out the following example. Click one circle, then drag and release on top of the other circle:

The circle you released the mouse on top of will turn red, as specified in Path.onMouseUp()

Now, try the exact same example but with Path.onMouseDown() included:

The behavior changes: onMouseUp fires for both circles.

Curious if this is intended behavior or not. I'm guessing not, it seems to break what the API specifies.

Yes I agree, this is strange. I need to look into what's causing it. Thanks for spotting it!

I think the only situation where this behavior makes sense is when an item defines a onMouseDrag() event. Then I would expect to receive the onMouseUp() wether it is inside or outside of the item (this is also the case why it was implemented it in such a way). This can be easily fixed.
