Can preset-commonmark and preset-gfm be used together?

I used to think the preset-commonmark and preset-gfm are complement to each other, I use both of them before. But after trying upgrading them from 5.3.0 to 5.5.0, I got this error:

RangeError: Adding different instances of a keyed plugin (MILKDOWN_PLUGIN_ID$)
    at state.js:50:15
    at Array.forEach (<anonymous>)
    at new Configuration2 (state.js:48:26)
    at Function.create3 [as create] (state.js:184:19)
    at editor-state.ts:65:35
    at async Promise.all (index 54)
    at async _Editor.create (editor.ts:86:35)

So now I have to choose to keep preset-commonmark or preset-gfm, I wonder is it not a bug? Is that mean the two plugins are confilct to each other?

preset-gfm has already includes everything in preset-commonmark.

By the way, I used to write this kind of code:

import { heading } from '@milkdown/preset-commonmark'
export const myHeading = heading.extend((original, utils, options) => {
  // ...
}

And I realized that I cannot simply migrate it like that:

import { heading } from '@milkdown/preset-gfm'
export const myHeading = heading.extend((original, utils, options) => {
  // ...
}

That would give an error, is that mean preset-gfm does not allow the extend grammar like this?

I think extend should work as usual, what's the error you got?

I cannot recreate this error, it now works fine😄 the error I met that day was possibly caused by a temporary unawareness of my IDE.
thank you for your reply.
