I think that: - what it calls "needs triage" is currently called "new" - what it calls "in discussion" is currently called "in progress" - what it calls "patch ready" and "needs MFC") no longer exist or aren't used currently (although see the patch-ready for the former) - what it calls "issue resolved" is currently "closed" with resolution "fixed" but I can't swear to it. While there, maybe review the rest of it for currency. Spotted while rooting around for when/why to MFC info.
Thanks for the report. Known issue for a while, hadn't tracked it in Bugzilla, thank you for reporting. Happy to address these issues via an issue management page on the wiki, from which a correct/accurate summary can be added on the website
(In reply to Kubilay Kocak from comment #1) Link me? I'll see what I can do beyond my educated guesses above.
