process.nextTick 在 Promise.resolve().then 之前？

Question

下面的代码：

\n

process.nextTick( () => console.log("nextTick 1") );\nprocess.nextTick( () => { \n    console.log("nextTick 2"); \n    Promise.resolve("Resolved promise inside nextTick").then(console.log); \n})\n\nPromise.resolve("Resolved promise 1").then(console.log);\nPromise.reject("Rejected promise 2").catch(console.log);\n\nsetImmediate( () => {\n    console.log("setImmediate");\n    Promise.resolve("Resolved promise inside setImmediate").then(console.log);\n    Promise.reject("Rejected promise inside setImmediate").catch(console.log);\n    process.nextTick( () => console.log("nextTick 3") );\n})\n

\n

在节点 v14.17.0 中输出此内容

\n

Resolved promise 1\nRejected promise 2\nnextTick 1\nnextTick 2\nResolved promise inside nextTick    \nsetImmediate\nnextTick 3\nResolved promise inside setImmediate\nRejected promise inside setImmediate\n

\n

为什么前两个 Promise.then/catch 回调在 process.nextTick 回调之前调用？\xc2\xb4t process.nextTick 回调应该像 setImmediate 部分一样先于 Promise 回调吗？

重现此行为的最简单方法（节点 14+、16+、18）：

package.json只需使用以下几行将新内容添加到同一文件夹：

{
  "type": "commonjs" //I assume you have here "module"
} 

对于 commonJS，输出是预期的。

不幸的是，目前还没有一个很好的解释，这里有更多讨论
