Safari 3.1 on Windows XP shows the green area. Releases r30466 and up don't.
Created attachment 21030 [details] test case
Created attachment 459983 [details] Safari 15.5 matches other browsers I am unable to reproduce this in Safari 15.5 on macOS 12.4 and as shown in the picture, it matches other browser. I think down the line, it got fixed and now can be marked as "RESOLVED CONFIGURATION CHANGED". Thanks!
Update - if I resize Safari in horizontal width, "Green" from the attached test case goes away and it matches Firefox, which do same. Although "Chrome Canary 104" keep on showing showing green in the test case. So please retest accordingly.
Interesting, I don't see that behavior on resizing with Chrome 102.0.5005.61. Did min-width break in Chrome beta?
