Description

We're proposing a new DOM primitive, Node.prototype.moveBefore, a drop-in replacement for Node.prototype.insertBefore, that allows moving elements in a node tree without incurring state-resets. See details at the explainer and at https://github.com/whatwg/dom/issues/1255. Would love to shape this together with WebKit + Mozilla.

I suggest we resolve this as "position: support" one week from now. There are a couple of design aspects that will need to be worked through, such as handling animations and creating a suitable mutation record, but overall this looks like the correct way to add a new tree primitive to the DOM.
