/**
* @assertion In an unmigrated library, override checking is done using legacy
* types. This means that an unmigrated library can bring together otherwise
* incompatible methods. When choosing the most specific signature during
* interface computation, all nullability and requiredness annotations are
* ignored, and the [Never] type is treated as [Null].
*
* @description Check that if legacy class extends opted-in class, legacy method
* with optional named argument without default value can override method
* with [required] argument and defaut argument value is treated as [null] in
* this case.
