Version-Release number of selected component (if applicable):
ER5

How reproducible:
always

Steps to Reproduce:
1. create or open process with a task node (or any other activity node that is resizable)

the handles have a vertical offset relative to the corners of the rectangle that wraps a node

Expected results:
the handles should lie on an imaginary rectangle that is a few points larger than the visible one and has identical centre (I think it used to be that way)
