| <title>DOM Traversal: NodeIterator: Removal of nodes that should have no effect</title> |
| <!-- |
| This tests these cases that should have no effect: |
| 1. Remove a node unrelated to the reference node |
| 2. Remove an ancestor of the root node |
| 3. Remove the root node itself |
| 4. Remove descendant of reference node |
