Safari 15.3: Offline HTML files don't display images when dropped into Safari.
When developing websites, I always used to be able to drop an offline HTML file onto Safari and it would display, with images. With Safari 15.3 (and OS 12.2.1) that no longer works - the images don't display. It does still work in Chrome. (Disable Images is NOT checked in the Develop menu, so that's not the problem. Besides, the same pages display fine when they're accessed online.)
Any way to fix this?
