Function `length` attribute not inferred in presence of static `length` method
info: |
ClassTail : ClassHeritage_opt { ClassBody_opt }
14. If constructor is empty, then [...]
b. Let F be ! CreateBuiltinFunction(steps, 0, className, « [[ConstructorKind]], [[SourceText]] », empty, constructorParent).
15. Else,
a. Let constructorInfo be ! DefineMethod of constructor with arguments proto and constructorParent.
[ This sets the length property on constructorInfo.[[Closure]]. ]
b. Let F be constructorInfo.[[Closure]].
[...]
25. For each ClassElement e of elements, do
a. If IsStatic of e is false, then [...]
b. Else,
i. Let field be ClassElementEvaluation of e with arguments F and false.
[ This overwrites the length property on F. ]
