Has this been merged into upstream? I have n.parentNode.replaceChildren successfully executed but TypeScript reports error:

TS2339: Property 'replaceChildren' does not exist on type 'ParentNode'.

for the following code:

function mount(n: Node) {
	for (let p = n.parentNode; p != null && p.nodeName != "HTML"; p = p.parentNode) {
		(<ParentNode>p).replaceChildren(n)
		n = p
	}
}

Also if I don't force casting (<ParentNode>p), it reports:

TS2339: Property 'replaceChildren' does not exist on type 'Node & ParentNode'.

Don't know why.

Well, don't compile in production mode. I have to use type casting (<any>p).replaceChildren(n) for it to build.

This was fixed back in #44684 for TS 4.4+. The examples in this thread all compile. Playground Link
