Description
Hi,
I figured out that in Sankey diagram, if the links overlap, sometimes certain links go in the background and become inaccessible. Here is my codepen for the reported case: (https://codepen.io/mateo-forjan/pen/NWZWyPd).
Trying to access link info for links 1->4 and 2->4 is impossible from the inside of the link 3->4 because it seems those are in the background of the mentioned link. Sometimes, there can be a situation where one link from the background can be accessed and another one cannot.

Research direction
Start by reproducing the overlapping-link case from the linked CodePen in a Sankey plot. Then trace the Sankey link interaction or hit-testing entry point and determine how links 1→4, 2→4, and 3→4 are layered. Done means every overlapping link can be accessed and its information inspected; the issue names no repository file or test to run.
