chore(deps-dev): bump jsdom from 25.0.1 to 29.1.1

[dependabot]

Bumps jsdom from 25.0.1 to 29.1.1.

Release notes

Sourced from jsdom's releases.

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• Fixed getComputedStyle() sometimes returning outdated results after CSS was modified.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.
• Fixed XMLHttpRequest's response getter returning parsed JSON during the LOADING state instead of null.
• Fixed getComputedStyle() crashing in XHTML documents when stylesheets contained at-rules such as @page or @font-face.
• Fixed a potential hang in synchronous XMLHttpRequest caused by a race condition with the worker thread's idle timeout.

v28.1.0

• Added blob.text(), blob.arrayBuffer(), and blob.bytes() methods.
• Improved getComputedStyle() to account for CSS specificity when multiple rules apply. (@​asamuzaK)
• Improved synchronous XMLHttpRequest performance by using a persistent worker thread, avoiding ~400ms of setup overhead on every synchronous request after the first one.
• Improved performance of node.getRootNode(), node.isConnected, and event.dispatchEvent() by caching the root node of document-connected trees.
• Fixed getComputedStyle() to correctly handle !important priority. (@​asamuzaK)
• Fixed document.getElementById() to return the first element in tree order when multiple elements share the same ID.
• Fixed <svg> elements to no longer incorrectly proxy event handlers to the Window.
• Fixed FileReader event timing and fileReader.result state to more closely follow the spec.

Greptile Summary

Dependabot bump of jsdom from 25.0.1 to 29.1.1, a dev-only testing dependency used by Vitest's optional jsdom environment pragma. The lock file is regenerated with updated transitive CSS-parsing packages.

• package.json: single-line version range change from ^25.0.1 to ^29.1.1.
• package-lock.json: jsdom 29 pulls in a new CSSOM stack (css-tree, @asamuzakjp/*, @bramus/specificity) and bumps all @csstools/* packages; these collectively raise the minimum Node 20.x requirement from any 20.x to 20.19.0+.
• jsdom 29.0.0 also introduced bad-port blocking per the fetch spec — no tests in this repo make HTTP fetches through jsdom directly, so no test breakage is expected.

Confidence Score: 4/5

Safe to merge — jsdom is a dev-only testing dependency and is not used in the production bundle; the CI workflow resolves node-version: 20 to the latest 20.x, which satisfies the raised engine floor.

The bump is straightforward and limited to the test toolchain. The only non-trivial change is that several transitive CSS packages now declare a Node 20.19+ engine minimum, where the repo previously had no stated lower bound. The CI setup should be unaffected at runtime, but the lack of a pinned Node version file means a contributor on an older 20.x patch release could hit unexpected engine warnings locally.

package-lock.json — worth a quick scan for the new transitive @asamuzakjp/* and @bramus/specificity packages if supply-chain policy requires it.

Important Files Changed

Filename	Overview
package.json	Bumps jsdom devDependency from ^25.0.1 to ^29.1.1; single-line change, correct range syntax
package-lock.json	Lock-file regenerated for jsdom 29.1.1; several transitive deps now require Node ^20.19.0

Transitive dep engine floor raised to Node ≥20.19.0

Several new jsdom 29 transitive packages (@asamuzakjp/css-color, @asamuzakjp/dom-selector, @asamuzakjp/generational-cache, @csstools/color-helpers, @csstools/css-calc, @csstools/css-color-parser, @csstools/css-parser-algorithms) all declare "node": "^20.19.0 || ^22.12.0 || >=24.0.0", up from the previous "node": ">=18". The CI workflow pins node-version: 20, which resolves to the latest 20.x at run time and should satisfy this, but there's no .nvmrc or .node-version file in the repo. Any contributor on Node 20.x < 20.19.0 will hit engine-requirement warnings (or failures if --engine-strict is set) when running npm ci locally. Adding a .nvmrc with 20.19 or higher would surface the requirement early.
