Thumbnail rotation in Safari 14.0.3

[sarahjeansweeney]

PY reported that this file had a flipped thumbnail when viewing the metadata page in Safari 14.0.3: https://repository.library.northeastern.edu/files/neu:bz60hf05j

The thumbnail for the file displays as expected in other browsers, and even in older versions of Safari (or, it displayed correctly in 13.1.2, at least). But the thumbnails 4 and 5 are flipped when viewed in Safari 14.0.3.

The expected display:

The display in Safari 14.0.3:

Other recently deposited PDFs display expected in Safari 14.0.3 (see an example: https://repository.library.northeastern.edu/files/neu:ww72bb684), but all files in the Sub-Series B. Urban Renewal collection have flipped size 4 and 5 thumbnails. The PDFs in this collection were scanned as TIFFs and uploaded as PDFs, and the exif Orientation tag is "Unrecognized" (according to IMageMagic, anyway. Exiftool thinks its "Unknown"), so the files themselves are certainly playing into this issue.

This looks like something I've seen many times before. Where someone looking at an image in some image viewer has a rotate or flip or somesuch. And they think that that's changed settings on the file itself, but the viewer just saves settings for the image internally, which doesn't transfer the changes to other places, and other places try to manage it differently. That exif Orientation tag especially makes me give a side-eye in that direction. Not sure what the best for-realzies image editing tool to point them to. That's just my first guess.

I downloaded the image, and locally opening it in my default file viewer and GIMP looked as expected.
