Review Comment:
I think the duplication is created as a byproduct of changing source and
targets from tasks to parent task groups when task groups are collapsed. There
end up being duplicate edges as that transformation occurs. This deduplication
is handled on the front end when a user interacts with the UI. If I recall,
collapsing task groups doesn't create any backend requests, does it?
