I've attached a couple reduced test cases. In the failing test case the html element has overflow-x:hidden and the body has a height of 100%. Regardless of scroll position, body reports a scrollTop of 0 at all times. Removing either the overflow-x hidden on html or the height on body result in the body element reporting scrollTop correctly, as can be seeing in the working case. To reproduce: 1. Open failing-case attachment. 2. Scroll down any amount and click the Report scrollTop Values button. 3. Compare the results to the same steps using working-case attachment.

RESULTS from "Failing test case" across all browsers: *** Safari 15.6 on macOS 12.5 *** BODY scrollTop: 0 HTML scrollTop: 0 *** Firefox Nightly 105 *** BODY scrollTop: 0 HTML scrollTop: 0 *** Chrome Canary 106 *** BODY scrollTop: 0 HTML scrollTop: 0 RESULTS from "Working test case..." across all browsers: *** Safari 15.6 on macOS 12.5 *** BODY scrollTop: 0 HTML scrollTop: 0 *** Firefox Nightly 105 *** BODY scrollTop: 0 HTML scrollTop: 0 *** Chrome Canary 106 *** BODY scrollTop: 0 HTML scrollTop: 0 ________ I am not sure whether spec changed or what but all browsers are not following web-spec but I am not able to reproduce and get same results across all browsers. As a result, I am going to mark this as "RESOLVED WONTFIX". Please reopen, if you think above results are wrong or I tested something incorrectly. Thanks!
