esbuild won't create a TDZ error when a class is referenced in its own computed property keys

[SukkaW]

With given code:

class A {
  static a = 1;
  static [A.a] = 2;
}

Here is the output of the esbuild (with --loader=js --target=es6 flag):

var __defProp = Object.defineProperty;
var __defNormalProp = (obj, key, value) => key in obj ? __defProp(obj, key, { enumerable: true, configurable: true, writable: true, value }) : obj[key] = value;
var __publicField = (obj, key, value) => {
  __defNormalProp(obj, typeof key !== "symbol" ? key + "" : key, value);
  return value;
};
var _a;
const _A = class {
};
let A = _A;
_a = _A.a;
__publicField(A, "a", 1);
__publicField(A, _a, 2);

And here is the output of the babel:

"use strict";

var _a;

function _classNameTDZError(name) { throw new Error("Class \"" + name + "\" cannot be referenced in computed property keys."); }

_a = (_classNameTDZError("A"), A).a;

var A = function A() {};

A.a = 1;
A[_a] = 2;

And here is the output of the swc:

function a(a, b, c) {
    return b in a ? Object.defineProperty(a, b, {
        value: c,
        enumerable: !0,
        configurable: !0,
        writable: !0
    }) : a[b] = c, a;
}
var c = (function(a) {
    throw new Error("Class \"A\" cannot be referenced in computed property keys.");
}("A"), b).a, b = function b() {
    "use strict";
    !function(a, b) {
        if (!(a instanceof b)) throw new TypeError("Cannot call a class as a function");
    }(this, b);
};
a(b, "a", 1), a(b, c, 2);

Both swc & babel output the correct result (where an error should be thrown).
