Error for duplicate Node Names cites sibling node name of the actual erroneous node's name

I'm not sure exactly how to reproduce this, but I imported a resource model and changed a node from being its own nodegroup to joining its parent nodegroup. For some reason this prompted a "Duplicate Node Name" error, but there is no evidence of that being the case (see video below).

I think I figured this out a bit. Basically there are two duplicate node names in the graph, called "Relationship Comments". However the error cites the duplicate as "Relationship From Date - Site" which is a sibling to the real duplicate. Therefore the issue seems to be that the Error is valid but the erroneous duplicate node name is not reported in the error. Instead for some reason it's the first sibling node's name that gets cited.
