I THINK THIS DID THE TRICK!  YAY!

also realized that if you take the heap profiles, you must go back to
the original state for there to be absolutely no detached dom trees.
but if you go from home to help, there will be 2.  but if you go back
to home, there will be none again.  whatever.
actually nevermind. but i cleared another annoying console.log

i guess the goal is just to be patient.  if you keep playing around and
keep clearing the memory (by doing the heap profiler) it'll eventually
clear out all garbage.
