When someone is clicking on the summary field or presses Enter both for a resolved topic, the whole discussion "collapses".
Reported by user with Chrome 52 and Edge on Windows 10, both logged-in and logged-out. Not reproductible on Linux with Chromium and Firefox. I think it is local. Still investigating.
- Resolve a topic that has a number of comments
- When the summary field appears, click it a bunch of times
- Observe the comments in the resolved topic alternate between appearing and disappearing every time you click
