Face tags don't seem to work for my photos

Describe the bug I tag my photos using DigiKam on linux (which supports XMP tag) and for some reason, your squirrel photo from the demo shows the face tag but not my photos.

Looking through the code, I don’t see any fields being used that aren’t in my photo, so I’m stumped. Any idea whats up?

Thank you @mattiasw, using the newer version indeed solved the issue.

Happy to contribute, I’m just not so great with frontend tools so I’ll be a bit slow. I looked through that file and found nothing being accessed that wasn’t in the metadata. It needs a step-through I suppose.
