Updates styled-components from 6.3.11 to 6.4.2

Release notes

Sourced from styled-components's releases.

styled-components@6.4.2

Patch Changes

• 9945904: Restore TypeScript prop autocomplete inside the JSX of a styled component once the first attribute is typed.
• 9945904: Apply all chain levels' styles when an extended styled component renders with the as prop under Preact's react-compat.
• 9945904: Respect a custom toString on plain value objects (e.g. design tokens) when interpolated into a styled component, rather than walking the object's keys as CSS declarations.
• 9945904: Fix a TypeScript error when wrapping a component whose props include an as prop with a non-string type (such as Next.js Link's as?: Url). The styled component now accepts either the styled-components polymorphism value or the wrapped component's own as type, so spreading the wrapped component's props onto the styled component is assignable again.
• 9945904: Restore reliable styling in production browser bundles built without a runtime process global.

styled-components@6.4.2-prerelease-20260516150535

styled-components@6.4.2-prerelease-20260514182414

• 9945904e: Restore TypeScript prop autocomplete inside the JSX of a styled component once the first attribute is typed.

• 9945904e: Fix a TypeScript error when wrapping a component whose props include an as prop with a non-string type (such as Next.js Link's as?: Url). The styled-components as and forwardedAs props now consistently override the wrapped component's same-named props instead of colliding with them.

• 9945904e: Restore reliable styling in production browser bundles built without a runtime process global.

styled-components@6.4.1

Patch Changes

• 49d09ae: Fix a performance regression in 6.4.0 where dynamic createGlobalStyle components caused significant re-render slowdowns. Also restores pre-6.4 cascade ordering when multiple instances of the same createGlobalStyle coexist.
• eca95b2: Fix outdated dev-mode error messages for keyframes-in-untagged-strings and component-selector references that still pointed at www.styled-components.com and described behavior from styled-components v3.

What: The version of 'postcss' has been updated from 8.4.39 to 8.5.15, which includes performance fixes.

Why: Performance improvements are crucial to maintain responsiveness, especially if postcss is being heavily utilized in styling or when processing large CSS files.

How: Monitor performance metrics after the update to ensure the changes have positively impacted build and runtime performance. Also, ensure to run a full suite of tests to catch any regressions affecting CSS processing.
