Summary: In quirks mode, body.clientHeight > body.offsetHeight when you put padding on the HTML element

It's not clear to me what the right thing to do here (whether they should be equal or have offsetHeight>clientHeight), but it's clear that the current behavior is wrong.

behaviour seems correct

http://dev.w3.org/csswg/cssom-view/#dom-htmlelement-offsetheight
http://dev.w3.org/csswg/cssom-view/#dom-element-clientheight

ClientHeight : viewport height
Offsetheight : renderer's height.

In all browsers (Chrome Canary 106, Firefox Nightly 104 and Safari 15.6 on macOS 12.5), body.clientHeight is great than body.offsetHeight using attached test case. I am not clear on web-spec or expected behaviour but since all browsers are aligned, I think we can mark this as "RESOLVED CONFIGURATION CHANGED" or "RESOLVED WONTFIX". Thanks!
