   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
