Once introduced the "growable" canvas support ( JBPM-5536 ), the shapes' magnets and connector bendpoints are not working fine, there are some bugs:

• Once a shape has been dragged outside the visible canvas area, it's not possible to change the source/target connection to other nodes, as the magnets do not appear
• When scrolling, and moving the mouse pointer over a connector, the blue marker bendpoint do not appear as with the mouse pointer, as it was before.
