Due to the fact that we only rolled out to 90% of users "ReadMore is not present in minerva stable" will fail sometimes if the user is bucketed in the 10% of users that don't have it :)
@pmiazga reading the code and based on the above (and the fact a new build is also green) I think your change has also applied the 90% to desktop users.. :-s

:/, could be, let me check the code

@Jdlrobson, @pmiazga: ^ Soooooo… Is RelatedPages enabled for 90% of desktop users?

@phuedx - nope

The nightly build has succeeded for two days in a row. The Fates surely smile upon us.

90% of beta feature users ;)

There's now no reason our browser tests should be passing for this reason anymore so this should be fixed but I can't verify as there's a new kid in town who's making all our browser tests red. See T123557.

I still see the original tests not passing: https://integration.wikimedia.org/ci/job/selenium-RelatedArticles/308/#showFailuresLink

Also, according to a comment at T123557, that problem is not related to these failures.

I opened T157711. The error is the same but not the cause.

T157665 is a different problem to the one in this ticket that is impacting ALL browser tests so this is back to sign off. We can verify this is fixed when T157665 is fixed.
