Bumps jsdom from 27.4.0 to 30.0.1.

Release notes

Sourced from jsdom's releases.

v30.0.1

• Fixed getComputedStyle() with calc() and other functions throwing an exception, which regressed in v30.0.0. (@​asamuzaK)
• Sped up up range operations on large documents (@​leonidaz)

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• Fixed getComputedStyle() sometimes returning outdated results after CSS was modified.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)

Thank you for contributing and for sharing your work. This PR is awaiting maintainer review; the automated review does not replace that step.

For the bounty issues, we review PRs in the order they were opened, under the terms on the issue. An earlier PR that misses an acceptance criterion does not block a later complete solution. Please include the checks you ran yourself, their results, your environment, and any limitations, if those details are not already in the PR.

We appreciate the time you have put into this.

jsdom 30 is a major upgrade for the web test suite, and this branch conflicts with main. We will take it in a separate dependency pass with the full web suite run on it.

No change: jsdom 30 waits for a dependency pass with the full web suite. The branch also still conflicts with main.
