chore(deps): bump jsdom from 28.0.0 to 29.1.1

[dependabot]

Bumps jsdom from 28.0.0 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• Fixed getComputedStyle() sometimes returning outdated results after CSS was modified.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.

Mogplex PR Review

Status: Attention needed

Routine devDependency bump for jsdom (28.0.0 → 29.1.1). No security or correctness issues found. Two warnings: new transitive dependencies raise the effective Node.js floor to 20.19.0, and jsdom v29's CSSOM overhaul warrants test validation before merge.

1 finding was added inline.

Warnings

• New transitive dependencies require Node.js ^20.19.0 (pnpm-lock.yaml)
  New transitive dependencies introduced by this bump—@asamuzakjp/css-color@5.1.11, @asamuzakjp/dom-selector@7.1.1, and @asamuzakjp/generational-cache@1.0.1—declare engines: {node: ^20.19.0 || ^22.12.0 || >=24.0.0}. The project has no .nvmrc or engines field in package.json, so there is no documented Node version floor. Developers running Node 20.18 or earlier will hit engine mismatch warnings from pnpm.

Warning: Major jsdom version includes CSSOM overhaul — validate tests

jsdom v29 includes a major CSSOM implementation overhaul—replacing @acemir/cssom and cssstyle with fresh internal implementations built on css-tree. This affects getComputedStyle(), shorthand parsing, and style mutation behavior. Since this project uses environment: "jsdom" in Vitest, any tests relying on computed styles or CSSOM edge cases could fail silently or produce different results.

[charlesrhoward]

Closing: jsdom@29 breaks the Vitest forks pool — every worker fails to start with TypeError: webidl.util.markAsUncloneable is not a function (jsdom 29's bundled undici/webidl is incompatible with the current vitest@4.1.6 + Node 20 setup). Not worth pinning around right now; revisit when Vitest catches up or we move to a Node version that ships a compatible undici.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
