  Test that when the parent DOM node of an accessible node subtree is removed,
  all accessible node subtree's AXVirtualObjects are removed immediately. So
  that the orphaned AXVirtualObjects (|axChild|, role="button" for this test)
  don't try to walk up parent chain and compute their parents and hitting
  DCHECKs.
