Can't connect elements vertically far from each other in a BPMN Diagram

https://github.com/kmacedovarela/heatmap-issue-reproducer Try to connect an element in the last lane, with the end node on the first lane. Actual result It is not possible to do that. Expected result It's possible to connect two nodes placed anywhere in the process. Details: If the target node is not visible in the process, the displayed process area is continuously adjusting according to mouse pointer (the view is scrolled in direction of pointer movement) while the sequence flow's arrow is selected.
