Obfuscation failed for code with `super`

Can be reproduced on online demo:

class BaseClass {
    constructor(foo) {
        this._foo = foo;
    }
  
      get foo() {
        return this._foo;
    }
}

class BarClass extends BaseClass {
    constructor(foo, bar) {
        super(foo);
         this._bar = bar;
    }
  
      get bar() {
        return this._bar;
    }
}

const a = new BarClass('foo', 'bar');
console.log(a.foo);
console.log(a.bar);

Attempt to obfuscate this code snippet with everything off and Mangle Variable Names on returns: Error: Unknown node type Super.

In the future i’ll remove esmangle on my own transformer.

Could it be the deadCodeInjection (again)?

Looks like ( Will fix it in 0.12.4
