--watch mode forgets original output target with nodenext

[DanielRosenwasser]

src/index.ts

import * as Thing from "thing";

Thing.fn();

tsconfig.json

{
 "compilerOptions": {
 "strict": true,
 "target": "es2020",
 "module": "nodenext",
 "moduleResolution": "nodenext",
 "outDir": "../dist"
 }
}

package.json

{
 "name": "some-proj",
 "version": "1.0.0",
 "description": "",
 "type": "module",
 "main": "index.js",
}

tsc --watch

First output:

import * as Thing from "thing";
Thing.fn();

Second output after a change/save:

"use strict";

 o[k2] = m[k];
}));
var __setModuleDefault = (this && this.__setModuleDefault) || (Object.create ? (function(o, v) {
 Object.defineProperty(o, "default", { enumerable: true, value: v });
}) : function(o, v) {
 o["default"] = v;
});
var __importStar = (this && this.__importStar) || function (mod) {
 if (mod && mod.__esModule) return mod;
 var result = {};
 if (mod != null) for (var k in mod) if (k !== "default" && Object.prototype.hasOwnProperty.call(mod, k)) __createBinding(result, mod, k);

const Thing = __importStar(require("thing"));
Thing.fn();
