Steps to reproduce: 1. open https://output.jsbin.com/bomiyur/quiet What is the expected result? The page is an image gallery that is implemented with and iframe and thumbnail links that target this iframe. In Firefox, when an image file is directly loaded into an iframe, the browser auto-scales the image to fit it into the iframe viewport. What happens instead? Chrome and Safari don’t do this. If they did, this no-JavaScript image gallery would become a real option.

Attached Test case in URL field. Chrome Canary 127 and Safari 17.5 have same behavior while Firefox Nightly 128 does scale and make it looks like image gallery view.
