In Sirius we have a functionnality allowing to expand the selection box around a border node when it is very small to facilitate the selection.

We have two cases regarding bordered node selection when it is connected to an edge.

Either the style of the node produces a visual size equals or greater than 20px. In this case, the bordered node selection box is the size of it.

Or the visual size of the node is below 20px. In this case we expand the selection box around it too have a minimum usable selection box that does not require that the user clicks a thousand times to select the border node.  

Currently the expansion of the selection box on a bordered node connected to an edge can expand over the selection box of an edge if the visual style is too small. 

In this case if the two bordered node are closed, it is possible to not being able to select the edge at all because the selections box of the two nodes are upon the selection box of the edge and have the priority over the edge selection. 

This cans happen with no zoom.

The problem with the zoom is that the realization of the expansion is currently based on the bordered nodes dimensions without zoom. So if we zoom and we have an acceptable box selection around the bordered node zoomed, we still expand the selection box with a width and edge based on the small visual version whereas we don't want too.
