Repro steps
- Open an article's talk page (try a featured article like Margaret Murray or something else with a sufficiently long history)
- Tap revision history in the top overflow more button
- Start scrolling the diffs
Expected behavior
- Paging should work as you scroll through the whole set of revisions
Actual behavior
- Paging fails and the error below is displayed
The failure is occurring in the first guard statement in private func parseSections(_ responseDict: [String: Any]) -> HistoryFetchResults? in PageHistoryFetcher.swift: assertionFailure("couldn't parse page history response")
