hiho,

i just got a fresh checkout/build in pursuit of an illusive
right-click bug, #168638.  there appears to be some new (between
feb.28 and now) unwanted behavior in connectors such as
generalizations in a UML class diagram...  they don't attach unless
you attach the non-arrow end first.  and then sometimes they fly off
the diagram...  could just be me  8-|

please ignore if you are already aware of this.
