Using BPMN, you often have an edge pointing at a pool instead of a particular node inside a pool. Although BPMN is normally left-to-right, we want to use top-to-bottom for display on a webpage. When BPMN layout is used with top-to-bottom selected, edges that point at a pool all get routed to the top or the bottom of the pool, instead of just horizontally to the nearest section of the pool like they would be in left-to-right layout.
Is this a bug? Am I doing something wrong?
