Bumps jsdom from 28.1.0 to 30.0.0.

Release notes

Sourced from jsdom's releases.

v30.0.0

Breaking changes:

  • Node.js minimum version raised to ^22.22.2 || ^24.15.0 || >=26.0.0.

Other changes:

  • Added CSS.escape() and CSS.supports() functions. (@​asamuzaK)
  • Added 'background-position-x' and 'background-position-y' CSS properties. (@​olagokemills)
  • Fixed getComputedStyle() to convert length values into pixels. (@​asamuzaK)
  • Fixed CSS function serialization, e.g., in the return value of getPropertyValue(). (@​asamuzaK)
  • Fixed the type of error thrown by document.evaluate() (@​dokson)

v29.1.1

  • Fixed 'border-radius' computed style serialization. (@​asamuzaK)
  • Fixed computed style computation when using 'background-origin' and 'background-clip' CSS properties. (@​asamuzaK)
  • Significantly optimized initial calls to getComputedStyle(), before the cache warms up. (@​asamuzaK)

v29.1.0

  • Added basic support for the ratio CSS type. (@​asamuzaK)
  • Fixed getComputedStyle() sometimes returning outdated results after CSS was modified. (@​asamuzaK)

v29.0.2

  • Significantly improved and sped up getComputedStyle(). Computed value rules are now applied across a broader set of properties, and include fixes related to inheritance, defaulting keywords, custom properties, and color-related values such as currentcolor and system colors. (@​asamuzaK)
  • Fixed CSS 'background' and 'border' shorthand parsing. (@​asamuzaK)

v29.0.1

  • Fixed CSS parsing of 'border', 'background', and their sub-shorthands containing keywords or var(). (@​asamuzaK)
  • Fixed getComputedStyle() to return a more functional CSSStyleDeclaration object, including indexed access support, which regressed in v29.0.0.

v29.0.0

Breaking changes:

  • Node.js v22.13.0+ is now the minimum supported v22 version (was v22.12.0+).

Other changes:

  • Overhauled the CSSOM implementation, replacing the @acemir/cssom and cssstyle dependencies with fresh internal implementations built on webidl2js wrappers and the css-tree parser. Serialization, parsing, and API behavior is improved in various ways, especially around edge cases.
  • Added CSSCounterStyleRule and CSSNamespaceRule to jsdom Windows.
  • Added cssMediaRule.matches and cssSupportsRule.matches getters.
  • Added proper media query parsing in MediaList, using css-tree instead of naive comma-splitting. Invalid queries become "not all" per spec.
  • Added cssKeyframeRule.keyText getter/setter validation.
  • Added cssStyleRule.selectorText setter validation: invalid selectors are now rejected.
  • Added styleSheet.ownerNode, styleSheet.href, and styleSheet.title.
  • Added bad port blocking per the fetch specification, preventing fetches to commonly-abused ports.
  • Improved Document initialization performance by lazily initializing the CSS selector engine, avoiding ~0.5 ms of overhead per Document. (@​thypon)
  • Fixed a memory leak when stylesheets were removed from the document.
  • Fixed CSSStyleDeclaration modifications to properly trigger custom element reactions.
  • Fixed nested @media rule parsing.
  • Fixed CSSStyleSheet's "disallow modification" flag not being checked in all mutation methods.
