The tree devtools uses is the light dom + pseudo-elements + NAC, but sometimes it wants to know stuff about the flat tree like assigned nodes. Previously it was using a weird mix of the anonymous vs. non-anonymous walkers to get what it wants, but that's needlessly complicated. Instead, make InspectorUtils.getChildrenForNode do the right thing, and add assigned nodes explicitly. While _getChildren using a walker might seem like a good idea for performance, realistically it was using InspectorUtils under the hood, and this is much simpler.
