4 years ago The bug is not directly connected to this feature, rather how svgs are drawn in the two browsers. In firefox the svgs of the UML elements are much bigger than the actual element, see screenshots. Because of that, the position of the element is calculated "wrong" and the wrong connection port is determined. Need to investigate more on this topic
Connecting UML elements does not work in Firefox in the lower right corner of the drawing area -> pointer event coordinates which should be relative to viewports, are incorrect -> wrong target port of connection is calculated
