Blur()	https://html.spec.whatwg.org/multipage/interaction.html#dom-window-blur: does nothing.
CancelAnimationFrame(uint)	https://html.spec.whatwg.org/multipage/imagebitmap-and-animations.html#animationframeprovider-cancelanimationframe
CancelIdleCallback(uint)	Cancels an idle callback (https://w3c.github.io/requestidlecallback/#the-cancelidlecallback-method). Does nothing when the handle is unknown.
CaptureEvents()	https://html.spec.whatwg.org/multipage/obsolete.html#dom-window-captureevents: does nothing.

Focus()	https://html.spec.whatwg.org/multipage/interaction.html#dom-window-focus: runs the focusing steps for the navigable of the window (its active document). As in the browsers, the document keeps its focused element (see `FocusModel.FocusNavigable`).
GetComputedStyle(Element, string?)	Returns the resolved values of the properties of an element or of one of its pseudo-elements (https://drafts.csswg.org/cssom/#dom-window-getcomputedstyle). The declarations are read-only and live: they reflect the current state of the document and of its style sheets.

PostMessage(object?, string, IReadOnlyList<object>?)	Posts a message to the window (https://html.spec.whatwg.org/multipage/web-messaging.html#dom-window-postmessage): a `message` event is fired at the window by a task, when its document has the origin `targetOrigin`.
Print()	https://html.spec.whatwg.org/multipage/timers-and-user-prompts.html#dom-print: there is no rendering, so it does nothing.
