I'm using the PR diffstat endpoint to check if any of the PRs have merge conflicts. I've noticed that for one PR that has a conflict when opened via web browser, there is no "merge conflict" status returned on that file when using the API. I've also tried adding `?topic=false` and `?topic=true` but it made no difference.
Additionally, when opening the PR from the browser, sometimes it takes a long time for the conflict information to show up (for the first 5-40 seconds the PR appears as if there is no conflict, then the conflict info box shows up). Is there some additional API that returns information about conflicts? Is this related to this change?
