TS2377 not reported when 'super' is called conditionally

Bug Report

The TS2377 error is reported when the constructor of a derived class does not contain a call to 'super'. However, it is not reported when only some branches contain the call but not others.

💻 Code

class CustomError extends Error {
  constructor(value: string | number) {
    if (typeof value === 'string') {
      super(value)
    } else {
      // oops, no super() call!
    }
  }
}

🙁 Actual behavior

TypeScript does not report any errors for the above code.

🙂 Expected behavior

TypeScript should report TS2377 for the above code, since 'super' isn't called in every branch.

Inizia con l'esempio Playground collegato e conferma la diagnostica TS2377 mancante quando non tutti i rami condizionali chiamano super. Traccia quindi la gestione da parte del compilatore TypeScript dei costruttori delle classi derivate e dei rami del flusso di controllo, poi aggiungi una copertura che mostri che TS2377 viene segnalato a meno che ogni ramo non chiami super.
