--- Comment #2 from Mike Wyrzykowski <mwyrzykowski at apple.com> ---
I investigated and it appears this site is using three.js and three.js is simulating a click event to display the USDZ blob.

In iOS 17.5, simulated click events will trigger the download path which is why you see the new behavior.

We will ask three.js if they can open the blob directly from the user action, which would avoid the download path behavior.
