Uploading ZIP file results in Image/Media files error

[sms-sudo]

When I upload a zip file able to mass import entities but images/media are listed as "This file type is not supported on image fields."

Images listed in the Attachments column for supporting files don't have this issue and are displayed normally. There is a buffer period in which the images/media are displayed:

but then subsequently load back into the error:

Is mass upload of images/media not supported yet in zip files if we want them to display outside of Primary Documents/Supporting files?

[sms-sudo]

I originally thought it could be that the images/media are not being uploaded (and perhaps #7460 following this issue, are actually not found instead of type not being supported), but as shown in test1 entity, the images that are shown under supporting documents are the same as those that should be displayed.

@RafaPolit to check if assigning images/media through CSV import is supported.
