Invalid output for class with `.prototype.constructor` deleted

[overlookmotel]

Input:

class C {}
delete C.prototype.constructor;
export default C;

Output:

export default Object.defineProperties(
  class C {},
  {prototype: {value: {}}
});

This output throws error TypeError: Cannot redefine property: prototype.

The output would be correct if C was a function, not a class. Problem is that the prototype property of classes is not writable or configurable (unlike functions).
