//   - `kind != NONE` checks whether the node appears in the native tree.

  // (e.g. because it's a ViewGroup). Note that it's okay if the node doesn't support children. When

  // HierarchyManager will catch this case and throw an exception.

  // because it isn't a ViewGroup). Consequently, its children need to be hosted by an ancestor.
