zoom images not showing up at all on Safari (desktop or iOS)

[bjhewitt]

Hi, all. I added this as an issue (#896), but I thought I'd try the community forum as well. I'm having an issue with zoom images not showing up at all on Safari, both desktop (safari 17.2.1) and iOS (17.2.1). There are no console or network errors - it's just an empty white space. Example at https://romanglassblowingdev.cmog.org/catalogue/objects-based-on-long-necked-vessel-processes/catobj--45/

I had hoped this might be an issue related to ids or filenames with periods in them, but I've renamed everything was dashes and underscores and it doesn't seem to make any difference (and would be weird anyway since it's limited to Safari).

My un-researched guess is that maybe Safari has some kind of privacy addition to webkit that's blocking something (?).
