  @param {Set<*>} set1 The 1st set to compare.
  @param {Set<*>} set2 The 2nd set to compare.
  @param {Map<Object, Object>} traversedValues A map of non-primitive values
  traversed in the first structure to their equal counterparts in the
  second structure.
  @return {boolean} {@code true} if the sets are equal.
