I'd hate if Explorers were not able to keep their state when the explored 
obejcts changed. This would make it impossible to explore an object, 
change its structure, then open another explorer on it to compare the old 
state with the new.
I haven't checked this new "reselect to refresh" feature, but I think it 
breaks what I described above.
