bors-servo b08d4a7d39 Auto merge of #14839 - Permutatrix:iss-12939, r=emilio
Make offset parent queries less buggy.

<!-- Please describe your changes on the following line: -->
Offset parent queries, which are used in the getters for HTMLElement's `offsetParent`, `offsetTop`, `offsetLeft`, `offsetWidth`, and `offsetHeight`, are pretty busted. The most egregious bug is that, as reported in #12939, inline elements are treated as if they're not present in the document. This PR fixes that and all of the other bugs I could trace directly to the offset parent query code, but `offsetTop` and `offsetLeft` are still unreliable in certain circumstances for reasons I haven't looked into (#13708). Inline elements with no content are still treated as not present due to #13982, so #13944 isn't fixed with this PR, either.
