Created attachment 461545 [details] Safari 15.6 matches with other browsers Based on the URL test case - as can be seen from attached screenshot, all browser (Chrome Canary 106, Firefox Nightly 105 and Safari 15.6) render this same. Considering all are interoperable. I am going to mark this as "RESOLVED WONTFIX". Please reopen, if you believe this is something yet to be fixed and all browsers are not aligned to web-spec. Thanks!
