Review comment:
       This one is much more opaque to me and this seems more risky than the other pieces of logic in this PR.  I checked and there is not unit test on this method. Can we either 1) write a covering unit test that works before/after or 2) minimize the changes. 
   
   It looks like there are existing fixtures for `controlPanelSections` that can be refactored out of superset-frontend/spec/javascripts/explore/controlUtils_spec.jsx .
