Interface share delete problem

[mattpascoe]

If you have an interface share that contains more than two entities.. i.e you have shared an interface to more than one other node, there is a bug in deleting the nodes.

to recreate. hover the bold shared interface that has at least two items that you could delete. If you try to delete the last (bottom) share, it will actually delete the first in the list instead.

Deleting the top deletable item in the list will work fine of course.
