The scenario "For a moderated post, a mode cycle with no user override keeps it hidden" is broken. Its background creates then hides a topic, and then the test asserts
Given I am on Flow page Then I should not see a moderated message on the first moderated topic
In fact the moment Flow reloads a page (the "Given I am on Flow page"), the hidden topic that this test creates vanishes altogether. Often there happens to be a locked topic (which remains visible) lower down on the page, and the test finds it and fails at
features/collapse.feature:65:in `Then I should not see a moderated message on the first moderated topic'
So the test is irrelevant[1] and it intermittently fails.
I rewrote the test in gerrit 164720 to "remove moderated notion from collape tests". But we will remove the collapse switcher feature (Topics and posts > Topics only > Small topics) altogether when we implement a TOC for Flow boards, so it's probably easier to just kill that one part of the test right now.
[1] The actual feature to test is unrelated to collapsing, it is
Given I hide (or delete or suppress) a topic Then ... When I reload the page Then I should not see hidden, deleted, or suppressed topics
gerrit 164655 is a step towards this.
