description: SuperProperty's behavior as a non-strict reference
info: |
  [...]
  4. If the code matched by the syntactic production that is being evaluated is
     strict mode code, let strict be true, else let strict be false.
  5. Return ? MakeSuperPropertyReference(propertyKey, strict).

  12.3.5.3 Runtime Semantics: MakeSuperPropertyReference

  1. Let env be GetThisEnvironment( ).
  2. If env.HasSuperBinding() is false, throw a ReferenceError exception.
  3. Let actualThis be ? env.GetThisBinding().
  4. Let baseValue be ? env.GetSuperBase().
  5. Let bv be ? RequireObjectCoercible(baseValue).
  6. Return a value of type Reference that is a Super Reference whose base
     value component is bv, whose referenced name component is propertyKey,
     whose thisValue component is actualThis, and whose strict reference flag
     is strict.

  6.2.3.2 PutValue

  [...]
  5. If IsUnresolvableReference(V) is true, then
     [...]
  6. Else if IsPropertyReference(V) is true, then
     a. If HasPrimitiveBase(V) is true, then
        [...]
     b. Let succeeded be ? base.[[Set]](GetReferencedName(V), W,
        GetThisValue(V)).
     c. If succeeded is false and IsStrictReference(V) is true, throw a
        TypeError exception.
     d. Return.
