### CSS

No notable changes.
- The [`&` selector](/en-US/docs/Web/CSS/Nesting_selector) inside {{cssxref("@scope")}} no longer inherits the [specificity of the scope start selector](/en-US/docs/Web/CSS/@scope#specificity_in_scope).
This makes `&` selectors in `@scope` consistent with [CSS nesting](/en-US/docs/Web/CSS/CSS_nesting), avoiding unexpected specificity differences (see [CSS nesting and specificity](/en-US/docs/Web/CSS/CSS_nesting/Nesting_and_specificity)).
