Yeah, that's a bug in the ECMAScript spec, it should be fixed by tc39/ecma262#2216.

Relevant spec section: https://tc39.es/ecma262/#sec-runtime-semantics-classdefinitionevaluation

If constructor is empty, then

If ClassHeritageopt is present, then

Let constructorText be the source text

constructor(...args) { super(...args); }
