Tried to reproduce but not sure I understand the problem. I flipped an image stored locally using the native image editor. (Since there is no option in our UI to flip it after you selected an image.) Both were uploaded in the orientation I expected. Also used the camera to snap some pictures in landscape and portrait mode and both also uploaded just fine:

How can you flip an image such that it's only stored in EXIF data to trigger this bug?

JPEGs store orientation info in EXIF data: https://jdhao.github.io/2019/07/31/image_rotation_exif_info/
They upload images from their computer/phone that are in one orientation and we display it in the other orientation (because we scrub out the orientation info).
