I am able to reproduce this bug in Safari Technology Preview 152 and Safari 15.6.1 on macOS 12.5.1 using attached test case and it shows "2x" and "1x" while all other browsers show "2x" and "2x". Weirdly. on iOS 15.6.1 on iPhone 13 Pro Max, it shows "3x" and "1x". Just wanted to share latest testing results. Thanks!

Based on a Twitter conversation, I've opened bug 244815. This seems very similar.
