#2187 validationMessage returns an empty string for built-in constraint violations

#2424 @happy-dom/jest-environment leaks the Window on teardown: window.close() is a no-op for the top-level window

#2420 Hangs indefinitely in isInclusiveAncestor when an element defines its own `host` property

#2419 getComputedStyle() flattens ancestor custom properties, turning a legal cross-element var() chain into a false cycle

#2416 FormData.set() doesn't remove duplicate entries with the same name

#2414 `FormData` only adds one entry for a `<select multiple>` with several selected options

#2409 Comment data is entity-decoded when parsing

#2407 Comment end tag is not detected when it overlaps a comment start tag

#2412 Animation.cancel() rejects the finished promise without marking it handled, surfacing an unhandled rejection in Node

#2411 `[hidden]` elements are not `display: none` in `getComputedStyle()`

#2404 CSSStyleDeclaration discards -webkit-line-clamp and its JavaScript aliases

#2403 Element.animate() finished effects are not reflected in computed styles and bypass fake timers

#1613 Style object must include dashed properties

#2363 CSSStyleDeclaration.setProperty() is O(n) per call, so building a declaration is O(n²)

#2344 Regression in 20.12.1: only the first var() in a value is resolved, shorthand with multiple var() is dropped from getComputedStyle()

#2351 getComputedStyle() resolves only the first var() occurrence in a declaration

#2366 Computed style cache is only invalidated one level deep, descendants keep stale inherited values (regression in 20.14.0)

#2401 Regression in 20.12.1: `-webkit-text-fill-color` is missing from getComputedStyle, even set to a literal

#2400 Regression in 20.13.1: `color: inherit` is ignored when an earlier declaration set a value (incomplete fix for #2347)

#1810 Erroneous behavior when using `DOMPurify` with `happy-dom`

#2399 Input type `number` cannot `stepUp()` or `stepDown()` decimal `step` value

#2182 `Node.prototype.nodeName` getter returns `''` when invoked on an element (breaks DOMPurify ≥ 3.4.8 anti-clobbering)

#2339 Animation.cancel() causes an unhandled rejection when finished is never read

#2397 Checked `<input type="radio">` added via innerHTML does not uncheck the rest of its group

#2396 HTMLElement.click() is missing the spec's click-in-progress flag — re-entrant click() recurses to "Maximum call stack size exceeded"
