deps(frontend): bump jsdom from 26.1.0 to 30.0.1

[dependabot]

Bumps jsdom from 26.1.0 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• Fixed getComputedStyle() sometimes returning outdated results after CSS was modified.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)

Blocked on an upstream jsdom regression, not on anything in this repo.

frontend-test fails one spec: WorkflowEditorView.test.ts > badges unavailable node types in the palette, with Cannot call trigger on an empty DOMWrapper at wrapper.find('.workflow-editor header button').

The wrapper root element is section.workflow-editor, and the button exists. Per DOM, el.querySelectorAll(sel) matches descendants of el with the selector evaluated against the whole tree, so .workflow-editor header button must match. jsdom 30 returns nothing.

Minimal reproduction, no Vue and no test framework involved:

const { JSDOM } = require('jsdom')
const { document } = new JSDOM('<!doctype html><html><body></body></html>').window

const section = document.createElement('section')
section.className = 'root'
section.innerHTML = '<header><button>x</button></header>'
document.body.appendChild(section)

section.querySelectorAll('.root header').length         // 1
section.querySelectorAll('.root header button').length  // 0  <-- should be 1
section.querySelectorAll('header button').length        // 1

jsdom	.root header	.root header button	header button
26.1.0	1	1	1
30.0.1	1	0	1

Same result whether the subtree is attached to the document or detached. Two compound selectors resolve correctly; adding a third descendant step where the scoping element is the first compound returns an empty list.

Rewriting the assertion to wrapper.find('header button') would turn this PR green, and that is deliberately not being done. A selector engine that silently returns an empty result for a valid selector makes find(...).exists() assertions pass vacuously, so the upgrade would trade one visible failure for an unknown number of silent ones.

Holding this PR until the behaviour is fixed upstream. Node 24 LTS (#98) has landed, so the engine constraint raised in the earlier review of #95 no longer applies; this selector regression is the only remaining blocker.

[Isaries]

Upstream tracking: jsdom/jsdom#4227, opened today, still open. Same reproduction and the same Vue Test Utils symptom, with the regression bisected to 29.1.1 (correct) -> 30.0.1 (empty NodeList). Our jsdom 26.1.0 measurement above agrees. No separate issue filed and no duplicate comment added there, since that report already carries everything this one would.

Keeping this PR blocked until #4227 is resolved.
