Viewer does not advance to next photo in a nested shared folder; works in user's space and in final shared folder #2976
Description
Describe the bug
Viewer does not advance to next photo in a nested shared folder; works in user's space and when sharing the folder with jpegs. If you share Parent/Child and preview the images in Child via that public shared link, the images do not advance. If you share the Child folder directly, then you can advance through the photos.
Previews successfully render but it is when one attempts to open a photo (which does render) and then advance do the error present themselves. Console logs indicate the error occurs when trying to load the photo.
Relevant errors in the log:
- TypeError: can't access property "filename", h is undefined (on initial preview of image)
- TypeError: can't access property "mime", e is undefined (on attempts to advance)
To Reproduce
Steps to reproduce the behavior:
- Create a nested folder (example:
Parent/Child) whereChildcontains.jpegs - Share the
Parentfolder using a public link - Click to
Childfolder - Click on a photo (the image displays, though the console log says the file can't open)
- Click arrow to advance photo (on mobile, swipe to advance photo)
Expected behavior
See the next photo in the folder.

Additional info:
I tried with both the child folder name containing whitespace and not containing whitespace. It did not appear to have an impact on this issue.
