:botond, since you are the author of the regressor, bug 1689546, could you take a look?

Set release status flags based on info from the regressing bug 1689546

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

Set release status flags based on info from the regressing bug 1689546

Let's not do that. Release tracking isn't particularly important here, since the regressing change here was a change to the test (making us toggle a pref for the test), with zero user-facing impact.

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

Sorry, comment 9 was misguided; see bug 1837500 comment 5 for notes on why.

--> Restoring status flags and calling this wontfix for 116.
