| PASS getComputedStyle(document.querySelector("html")).backgroundColor is "rgb(255, 255, 255)" |
| PASS document.querySelector("html:nth-child(n of *), html:nth-child(n of :not(notThere)), html:nth-child(odd of *), html:nth-child(odd of :not(notThere)), html:nth-child(even of *), html:nth-child(even of :not(notThere))") is null |
| #test-tree initially match when it is attached to the document |
| PASS document.querySelector("#test-tree:nth-child(n of *)") is document.getElementById("test-tree") |
| PASS testTree.matches("#test-tree:nth-child(n of *)") is true |
| After detaching #test-tree, :nth-child() no longer matches because it does not have a parent element. |
| PASS document.querySelector("#test-tree:nth-child(n of *)") is null |
| PASS testTree.matches("#test-tree:nth-child(n of *)") is false |
| PASS testTree.matches("#test-tree") is true |
