Steps to repro:

1. On ee-flow, visit http://ee-flow.wmflabs.org/wiki/Talk:Flow_Team_Retrospective
2. Change the view to small (right-most view toggle icon)
3. Scroll all the way down to the earliest topics on the page (past the first 10 that come preloaded)
4. Attempt to click on any topic below the 10 preloaded ones to expand – it will open as expected but then snap back shut after a second
5. Switch to collapsed view (middle icon), and you'll see the same behavior

This only seems to affect topics below the 10 earliest (so probably related to https://bugzilla.wikimedia.org/show_bug.cgi?id=56075). You can still switch to the all expanded view to expand all topics.
