containing super is eval code that is being processed by a direct eval that

ArrowFunction.
14.2.3 Static Semantics: Contains
With parameter symbol.
ArrowFunction : ArrowParameters => ConciseBody
1. If symbol is not one of NewTarget, SuperProperty, SuperCall, super or
this, return false.
2. If ArrowParameters Contains symbol is true, return true.
3. Return ConciseBody Contains symbol.
NOTE Normally, Contains does not look inside most function forms. However,
Contains is used to detect new.target, this, and super usage within an
ArrowFunction.
