When logging `new Map([[document.head, document.body]])` or `new Set([document.head, document.body])`, hovering over the <head>/<body> inside the inline (e.g. not expanded) `Map`/`Set` preview should highlight the <head>/<body>. Expanding the preview and hovering the <head>/<body> as a key/value will highlight the corresponding node as expected.
