Comment 4

[Daniel Holbert [:dholbert]]

(In reply to BugBot [:suhaib / :marco/ :calixte] from comment #2)

Set release status flags based on info from the regressing bug 1827329

Let's not do that. Release tracking isn't particularly important here, since it's not clear that this test-verify test failure issue has any user-facing impact.

--> Removing the version flags, so this isn't cluttering up dashboards of regressions that we just shipped in a recent version.

Comment 5

[Daniel Holbert [:dholbert]]

Gah, sorry; that just made this bug show up on a different release-management dashboard.

For reference: the first dashboard I was looking at for comment 4 was this bug list which is "bugs in layout component that have regression keyword and status-firefox116: affected, fix-optional". (i.e. regressions that we're shipping in version 116, which we haven't explicitly wontfix'ed for that version).

When I unset the status flags, this bug ended up showing up in the bugdash "important recent regressions without decision" triage section.

So: let's restore the status flags and just call this "wontfix" for 116, to reflect reality and to avoid cluttering up either dashboard, I think. (116 is currently beta, nearly release; it's unlikely we'd try to uplift a test-fix at this point, though we of course could if it were trivial and useful.)
