Bumps jsdom from 26.1.0 to 27.0.0.

Release notes

Sourced from jsdom's releases.

Version 27.0.0

Changes since 26.1.0

  • Node.js v20 is now the minimum supported version.
  • Added a variety of event constructors, even though we do not implement their associated specifications or ever fire them: BeforeUnloadEvent, BlobEvent, DeviceMotionEvent (omitting requestPermission()), DeviceOrientationEvent (omitting requestPermission()), PointerEvent, PromiseRejectionEvent, and TransitionEvent.
  • Added movementX and movementY to MouseEvent. (These are from the Pointer Lock specification, the rest of which is not implemented.)
  • Added customElements.getName(). (mash-graz)
  • Updated the virtual console:
    • "jsdomError" events are now documented, with specific type properties and other properties that depend on the type.
    • sendTo() was renamed to forwardTo().
    • The jsdomErrors option to forwardTo() can be used to control which errors are sent to the Node.js console. This replaces the previous omitJSDOMErrors boolean option.
    • "jsdomError"s for failed XMLHttpRequest fetches are no longer emitted.
    • The values that are printed when forwarding "jsdomError"s to the Node.js console are streamlined.
  • Switched our CSS selector engine from nwsapi to @asamuzakjp/dom-selector, closing over 20 selector-related bugs.
  • Upgraded tough-cookie, which now considers URLs like http://localhost/ to be secure contexts (per the spec), and thus will return Secure-flagged cookies for such URLs. (colincasey)
  • Upgraded cssstyle, which brings along many improvements and fixes to the CSSStyleDeclaration object and its properties.
  • Updated the user agent stylesheet to be derived from the HTML Standard, instead of from an old revision of Chromium.
  • Changed element.click() to fire a PointerEvent instead of a MouseEvent.
  • Changed certain events to be passive by default.
  • Changed the <input> element's pattern="" attribute to use the v regular expression flag, instead of u.
  • Fixed many specification conformance issues with the Window object, including named properties and changing various data properties to accessor properties.
  • Fixed document.createEvent() to accept a more correct set of event names.
  • Fixed the ElementInternals accessibility getters and setters. (They were introduced in v23.1.0, but due to inadequate test coverage never actually worked.)
  • Fixed using Object.defineProperty() on certain objects, such as HTMLSelectElement instances.
  • Fixed jsdom.reconfigure({ url }) not updating document.baseURI or properties derived from it. (This regressed in v26.1.0.)
  • Fixed CSS system colors, as well as the initial, inherit, and unset keywords, to resolve correctly. (asamuzaK)
  • Fixed CSS display style resolution. (asamuzaK)

Changes since 27.0.0-beta.3

  • Upgraded cssstyle, which brings along various CSS parsing fixes.

Version 27.0.0-beta.3

  • Breaking change: upgraded tough-cookie, which now considers URLs like http://localhost/ to be secure contexts (per the spec), and thus will return Secure-flagged cookies for such URLs. (colincasey)
  • Added customElements.getName(). (mash-graz)
  • Changed the <input> element's pattern="" attribute to use the v regular expression flag, instead of u.
  • Fixed jsdom.reconfigure({ url }) not updating document.baseURI or properties derived from it. This regressed in v26.1.0.
  • Fixed CSS system colors, as well as the initial, inherit, and unset keywords, to resolve correctly. This is especially important since the change in v27.0.0-beta.1 to use system colors in the user agent stylesheet. (asamuzaK)
  • Fixed CSS background property parsing and serialization. (asamuzaK)
  • Fixed CSS color parsing and serialization inside of gradients. (asamuzaK)
  • Fixed CSS display style resolution. (asamuzaK)
  • Upgraded @asamuzakjp/dom-selector, which notably fixed repeated use of the :scope selector. (asamuzaK)

Version 27.0.0-beta.2

Significantly improved specification conformance for the Window object, including named properties and changing various data properties to accessor properties. This is not likely to be breaking, but since it's a complex change to such a core object, we're happy to do another beta testing release with this included before graduating the v27 line to stable.

Additionally, updated cssstyle to v4.4.0, which brings along various conformance fixes to the CSSStyleDeclaration object and its properties.

Version 27.0.0-beta.1
