Bumps jsdom and @types/jsdom. These dependencies needed to be updated together.
Updates jsdom from 26.1.0 to 30.1.3

Release notes

Sourced from jsdom's releases.

v30.1.3

  • Improved performance of getComputedStyle() and computed CSS property reads, including with stylesheets containing attribute selectors. (@​scttcper, @​asamuzaK)
  • Fixed slowdowns when focusing elements and running interaction tests, which regressed in v30.1.2. (@​scttcper)
  • Fixed XMLHttpRequest reusing credentials supplied to xhr.open() after cross-origin redirects, including in response to authentication challenges from the destination.
  • Fixed XMLHttpRequest incorrectly sending and accepting cookies after cross-origin redirects back to the document's origin when xhr.withCredentials is false.
  • Fixed exceptions from malformed CSS math functions, such as calc(0px - @submenu_space), while parsing documents, stylesheets, and style declarations. (@​rnavarro)
  • Fixed getComputedStyle() ignoring style rules nested inside multiple @media rules.
  • Fixed CSS shorthands overwriting longhands with higher priority or specificity during style computation, including declarations containing CSS variables.
  • Fixed getComputedStyle() returning unresolved or inconsistent shorthand values, including for 'background', 'border', 'flex', 'font', 'margin', and 'padding', and incorrect shorthand defaults and inheritance.
  • Fixed computed background positions to resolve font-relative lengths using the final font size and handle multiple image layers correctly.
  • Fixed computed 'color' values depending on property read order, including unresolved color-mix() results, which regressed in v29.0.2.
  • Fixed currentcolor border colors incorrectly becoming transparent when 'color' uses light-dark() or relative color syntax.
  • Fixed CSS calculations that reduce to a percentage incorrectly producing pixel values, which regressed in v30.0.0.
  • Fixed numeric font weights in the 'font' shorthand incorrectly setting 'line-height'.
  • Fixed selector matching involving XML namespaces, and selectors such as [data-a|=""] failing to match empty values and values beginning with -. (@​asamuzaK)

v30.1.2

  • Updated URLs to support Unicode v18.0.0 in internationalized domain names.
  • Reduced package size and memory use for CSS property definitions. (@​scttcper)
  • Fixed severe slowdowns when building large DOM trees, including SVG charts with D3, which regressed in v30.1.0. (@​cmdcolin)
  • Fixed exponentially slow reads of empty inherited CSS custom properties in deeply nested documents, and custom properties incorrectly inheriting past an initial reset. (@​scttcper)
  • Fixed getComputedStyle() returning stale results after editing stylesheet declarations, selectors, or media queries, including in imported stylesheets.
  • Fixed selector matching and computed styles after changes to form control checkedness, indeterminacy, selection, values, and validity, including during form resets and canceled clicks.
  • Fixed computed styles for :focus, :focus-visible, :focus-within, and selectors containing them after focus changes, including inside focus and blur listeners. (@​asamuzaK)
  • Fixed element.focus() incorrectly focusing elements hidden by 'display', including through shadow hosts and slots, and elements excluded by shadow DOM slot assignment. (@​asamuzaK)
  • Fixed getComputedStyle() throwing for elements without inline-style support, including XML and MathML elements.
  • Fixed a memory leak where stylesheet parsing retained the last parsed stylesheet's window after window.close().
  • Fixed memory growth from long-lived MutationObserver instances retaining bookkeeping for garbage-collected nodes. (@​scttcper)
  • Fixed retained select.selectedOptions collections becoming stale after selection changes and form resets.
  • Fixed rejection of negative CSS sizing values, including for 'min-width', 'min-height', 'max-width', and 'max-height', which regressed in v30.1.0.
  • Fixed handling of deeply nested color-mix() expressions, including exceptions during color resolution. (@​asamuzaK)

v30.1.1

  • Fixed spurious window blur and focusout events and incorrect event.relatedTarget values when focusing an element after removing the previously focused element, which regressed in v30.1.0. (@​asamuzaK)
  • Fixed focus and blur behavior across frames, and focusing the document's viewport through document.documentElement.focus(). (@​asamuzaK)
  • Fixed focus targets removed or disabled by blur listeners becoming active, and text selections made by focus and blur listeners being overwritten. (@​asamuzaK)
  • Fixed element.focus() incorrectly focusing disabled form controls and <input type="hidden"> elements with tabindex="". (@​scttcper)
  • Fixed invalid style.setProperty() calls changing existing !important priorities, serialized styles, or mutation records. (@​FedgeNo)
  • Fixed !important handling when updating CSS longhands after shorthands, using variables or CSS-wide keywords, and assigning style properties directly. (@​FedgeNo)
  • Fixed <noscript> parsing with includeNodeLocations: true or inside frames to honor the runScripts option.
  • Fixed the storageQuota option being ignored by frames.
  • Fixed encoding detection of HTML and XML byte input to honor XML encoding declarations and detect UTF-16 without a byte order mark.
  • Fixed exceptions caused by truncated charset parameters in <meta> elements, and encoding detection incorrectly using incomplete <meta> tags. (@​FedgeNo)
  • Fixed XML serialization errors for namespaces named constructor, toString, __proto__, or "null", and incorrect reuse of namespace prefixes declared on sibling elements.
  • Fixed element.innerHTML and element.outerHTML in XML documents to reject invalid characters in attribute values and avoid stack overflows on large strings.
  • Fixed selector matching for :lang(), :nth-child(... of ...) after mutations, and :has() with duplicate IDs or nested logical pseudo-classes. (@​asamuzaK)

v30.1.0

jsdom is feeling the AGI!
