chore(deps-dev): bump jsdom from 26.1.0 to 28.1.0 in /src/microsoft-trydotnet-editor

[dependabot]

Bumps jsdom from 26.1.0 to 28.1.0.

Release notes

Sourced from jsdom's releases.

Version 28.1.0

• 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.
• Fixed a potential hang when synchronous XMLHttpRequest encountered dispatch errors.
• Fixed compatibility with environments where Node.js's built-in fetch() has been used before importing jsdom, by working around undici v6/v7 incompatibilities.

Version 28.0.0

• Overhauled resource loading customization. See the new README for details on the new API.
• Added MIME type sniffing to <iframe> and <frame> loads.
• Regression: WebSockets are no longer correctly throttled to one connection per origin. This is a result of the bug at nodejs/undici#4743.
• Fixed decoding of the query components of <a> and <area> elements in non-UTF-8 documents.
• Fixed XMLHttpRequest fetches and WebSocket upgrade requests to be interceptable by the new customizable resource loading. (Except synchronous XMLHttpRequests.)
• Fixed the referrer of a document to be set correctly when redirects are involved; it is now the initiating page, not the last hop in the redirect chain.
• Fixed correctness bugs when passing ArrayBuffers or typed arrays to various APIs, where they would not correctly snapshot the data.
• Fixed require("url").parse() deprecation warning when using WebSockets.
• Fixed <iframe>, <frame>, and <img> (when canvas is installed) to fire load events, not error events, on non-OK HTTP responses.
• Fixed many small issues in XMLHttpRequest.

Version 27.4.0

• Added TextEncoder and TextDecoder.
• Improved decoding of HTML bytes by using the new @exodus/bytes package; it is now much more correct. (ChALkeR)
• Improved decoding of XML bytes to use UTF-8 more often, instead of sniffing for <meta charset> or using the parent frame's encoding.
• Fixed a memory leak when Ranges were used and then the elements referred to by those ranges were removed.

Version 27.3.0

• Improved CSS parsing and CSSOM object APIs via updates to @acemir/cssom. (acemir)

Version 27.2.0

• Added CSSGroupingRule, CSSNestedDeclarations, CSSConditionRule, CSSContainerRule, CSSScopeRule, CSSSupportsRule, CSSLayerBlockRule, and CSSLayerStatementRule to jsdom Windows. (acemir)
• Improved CSS parsing and CSSOM object APIs via updates to @acemir/cssom. (acemir)
• Fixed @import-ed stylesheets to be properly exposed to CSSOM, and not to overwrite the sheet created from the <link> or <style> element. (acemir)

Version 27.1.0

• Improved CSS parsing by switching to @acemir/cssom, including support for nested selectors, nested declarations, layer statements, and improved at-rule validation. (acemir)
• Fixed some selector cache invalidation issues where changes to attributes were not being picked up. (asamuzaK)
• Fixed package.json "engines" field to reflect the new minimum Node.js versions needed to run jsdom, as noted in the changelog for v27.0.1.

Version 27.0.1

This release inadvertently raised the minimum Node.js version from v20.0.0 to v20.19.0+, v22.12.0+, v24.0.0+. (This happened via a dependency update.) This probably should have been a breaking (major) change, instead of happening in a patch version, since it prevents using earlier Node.js versions.

After further testing, we found that most of our development dependencies also require these versions, and so it's not feasible for the jsdom project to support earlier Node.js versions. (For example, our testing frameworks will not run on them.) If you need to use such earlier versions, or otherwise are working in an environment which gives related errors such as ERR_REQUIRE_ESM, then please stick with the v26.1.0 release of jsdom. (Noting, of course, that such versions are unsupported, and we will not respond to bug reports opened against them.)

Subsequent jsdom releases will explicitly require these minimum Node.js versions, and will have CI testing to ensure that the minimum version is not accidentally raised again.

🤖 Automated Major Version Review — APPROVED

Package: jsdom
Ecosystem: npm
Version change: 26.1.0 → 28.1.0 (major bump, skipping v27)

Research Summary

• Sources consulted:
  • https://github.com/jsdom/jsdom/releases — Reviewed release notes for v27.0.0–v28.1.0

  • https://github.com/advisories?query=jsdom — Checked for security advisories

Breaking Changes Analysis

jsdom 27.0.1 (Node.js version requirement):
The minimum Node.js version was raised to v20.19.0+, v22.12.0+, or v24.0.0+. The CI environment uses Node.js v20.20.0, which satisfies this requirement (20.20.0 >= 20.19.0). ✅

jsdom 28.0.0 (Resource loading customization overhauled):
The API for customizing how jsdom loads external resources was completely redesigned. However, inspection of all source and test files in src/microsoft-trydotnet-editor/ confirms that jsdom is not imported or used directly in any TypeScript/JavaScript file. It is listed as a devDependency, likely required by the test runner environment infrastructure. No custom resource loading code exists in this package. ✅

jsdom 28.0.0 (Known regression):
WebSockets are no longer correctly throttled to one connection per origin (due to a bug in nodejs/undici). This is noted in the changelog. The test suite does not use WebSockets through jsdom directly. ✅

Security Check

The GitHub Advisory Database shows 2 advisories for jsdom, both affecting older versions. No advisories affect jsdom 28.x. This upgrade moves away from the older affected versions.

Decision

✅ This major version update is safe to merge. CI checks pass, the diff contains only version file changes (package.json, package-lock.json), and no breaking changes affect this repository's usage of the package.
