Requesting an original-size thumbnail results in the new file. Purging the file page has no effect.
This issue is not limited to originals, it also affects thumbnails. https://upload.wikimedia.org/wikipedia/commons/thumb/d/dc/Public_art_-_GH_Piesse%2C_Katanning.jpg/220px-Public_art_-_GH_Piesse%2C_Katanning.jpg was previously affected by the Thumbor EXIF rotation bug, which was fixed a while ago. However, the thumbnail remained rotated and could not be purged. That problem resolved itself when I began typing up a Phab task, two days after it was first mentioned on 2020-06-22. The headers indicated that it was being served by Thumbor, not though ATS. The file is now being served through ATS. Unfortunately, I don't have the headers for any of that anymore.
