描述

Apologies if this is not the right place to post this. Although I'm sure this spec is ancient, is it not incorrect to report <body> as an offsetParent when the body is statically positioned, as it is by default?

This can easily be seen as unexpected behavior by creating an absolutely positioned element with bottom in a long document. The element is clearly positioned relative to documentElement, not `body.

研究方向
Investigate the CSSOM View specification regarding offsetParent behavior when body is statically positioned. Refer to the spec at https://drafts.csswg.org/cssom view/#dom htmlelement offsetparent. Review the behavior of absolutely positioned elements with bottom in a long document to determine if the current spec aligns with expected rendering.
