For round robin triage, bot needinfo'd person who is currently triaging, rather than the person who was responsible for triaging those bugs

I am on triage duty this week. I got needinfo'd on several issues facing the same problem, e.g.:
https://bugzilla.mozilla.org/show_bug.cgi?id=1778237

Because the severity was not set. However this bug is not in my queue:
https://bugzilla.mozilla.org/buglist.cgi?v2=2022-7-29&v3=2022-8-5&component=Graphics%3A%20Canvas2D&component=Graphics%3A%20Color%20Management&component=Graphics&component=Graphics%3A%20Layers&component=Graphics%3A%20Text&component=Graphics%3A%20WebRender&component=Graphics%3A%20Image%20Blocking&component=Graphics%3A%20ImageLib&product=Core&bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&keywords_type=nowords&o3=changedafter&f5=bug_severity&keywords=meta&o2=changedafter&emailassigned_to1=1&f6=bug_type&n3=1&email1=nobody%40mozilla.org&f3=creation_ts&o5=equals&query_format=advanced&v6=defect&f1=OP&f2=creation_ts&f4=CP&emailtype1=exact&o6=equals&v5=--&list_id=16162598

Instead it is in another person's queue from a few weeks ago:
https://bugzilla.mozilla.org/buglist.cgi?v2=2022-7-1&v3=2022-7-8&component=Graphics%3A%20Canvas2D&component=Graphics%3A%20Color%20Management&component=Graphics&component=Graphics%3A%20Layers&component=Graphics%3A%20Text&component=Graphics%3A%20WebRender&component=Graphics%3A%20Image%20Blocking&component=Graphics%3A%20ImageLib&product=Core&bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&list_id=16022721&keywords_type=nowords&o3=changedafter&f5=bug_severity&keywords=meta&o2=changedafter&emailassigned_to1=1&f6=bug_type&n3=1&email1=nobody%40mozilla.org&f3=creation_ts&o5=equals&query_format=advanced&v6=defect&f1=OP&f2=creation_ts&f4=CP&emailtype1=exact&o6=equals&v5=--

Ideally the person who should be needinfo'd is the person whose triage queue this belongs in according to the dashboard. Otherwise it provides the wrong incentives on clearing your triage queue in a timely manner :).

Start by tracing the round-robin triage needinfo logic and how it selects a bug's triage queue from the Firefox Graphics triage dashboard links. Confirm why it uses the currently assigned triager instead of the person responsible for the relevant queue. Done means needinfo goes to the queue owner identified by the dashboard, with coverage for the reported case.
