Thanks Wilson and Anne!

One interesting thing I noticed is that the algo relies on
candidate.distributedNodes already being correctly populated by the nesting
shadow tree. Does that mean that we'd need to ensure the correct order of
invoking distribution among the nesting trees? Or maybe mutation observers
already help you do that?
