For any element that anchors a `:has()` selector (i.e. Matches a selector that contains a `:has()` on its rightmost side), we prevent style sharing altogether, as evaluation of the `:has()` selector is required in the first place to determine style sharing. On the other hand, any element matching a rule containing `:has()` without anchoring it can do style sharing for siblings, but not cousins.

rust-selectors
CSS Selectors library for Rust. Includes parsing and serialization of selectors, as well as matching against a generic tree of elements. Pseudo-elements and most pseudo-classes are generic as well.
Warning: breaking changes are made to this library fairly frequently (13 times in 2016, for example). However you can use this crate without updating it that often, old versions stay available on crates.io and Cargo will only automatically update to versions that are numbered as compatible.
To see how to use this library with your own tree representation,
see Kuchiki’s src/select.rs.
(Note however that Kuchiki is not always up to date with the latest rust-selectors version,
so that code may need to be tweaked.)
If you don’t already have a tree data structure,
consider using Kuchiki itself.
