Pressing enter in an empty nested list item creates several more empty list items

[seeruk]

If you make a nested list, something like this:

* Hello
* World
  * Nested
  *

Then hit enter in that last empty item, you end up with something like this:

* Hello
* World
  * Nested
* 
*
  *

Note, this also happens in further nested lists, it just produces the same 3 empty nodes 1 level of nesting higher than the level you were at when you hit enter on the initial empty list item.

To Reproduce Steps to reproduce the behavior:

1. Enter the first markdown structure seen above
2. Hit enter in the empty (last) list item
3. See error

Edit: It also looks like you need to specify prosemirror-transform 1.2.5 in resolutions for this issue to occur, but a fresh install in a CRA project also exhibits these symptoms with the resolutions applied.

My package.json for the fresh CRA project

```json { "name": "my-app", "version": "0.1.0", "private": true, "resolutions": { "prosemirror-transform": "1.2.5" }, "dependencies": { "@testing-library/jest-dom": "^5.11.4", "@testing-library/react": "^11.1.0", "@testing-library/user-event": "^12.1.10", "@types/jest": "^26.0.15", "@types/node": "^12.0.0", "@types/react": "^16.9.56", "@types/react-dom": "^16.9.12", "react": "^16.14.0", "react-dom": "^16.14.0", "react-scripts": "4.0.3", "rich-markdown-editor": "^11.14.0", "styled-components": "^5.3.0", "typescript": "^4.1.2", "web-vitals": "^1.0.1" }, "scripts": { "start": "react-scripts start", "build": "react-scripts build", "test": "react-scripts test", "eject": "react-scripts eject" }, "eslintConfig": { "extends": [ "react-app", "react-app/jest" ] }, "browserslist": { "production": [ ">0.2%", "not dead", "not op_mini all" ], "development": [ "last 1 chrome version", "last 1 firefox version", "last 1 safari version" ] } } ```

Expected behavior It should probably step back up in list levels until it's at the top level then revert to an empty paragraph after that.

Version 11.14.0

Seems to be linked to #427 actually. I've removed the resolutions I added for prosemirror-transform and that fixes this list issue, but then I'm back to having the issue described in #427 with headings affecting the line above or below.

Edit: For now I've gotten around this by using these resolutions, basically just taking the versions from your package.json file:

{
    "resolutions": {
        "prosemirror-commands": "1.1.6",
        "prosemirror-dropcursor": "1.3.3",
        "prosemirror-gapcursor": "1.1.5",
        "prosemirror-history": "1.1.3",
        "prosemirror-inputrules": "1.1.3",
        "prosemirror-keymap": "1.1.4",
        "prosemirror-markdown": "1.4.4",
        "prosemirror-model": "1.13.3",
        "prosemirror-schema-list": "1.1.2",
        "prosemirror-state": "1.3.4",
        "prosemirror-tables": "1.1.1",
        "prosemirror-transform": "1.2.5",
        "prosemirror-utils": "0.9.6",
        "prosemirror-view": "1.18.1"
    }
}

With this both headings and lists work as expected. I'm not sure what it is that needs locking more tightly, but something seems to just be slightly off (maybe a bug in prosemirror, or they're not using semver?)

Thanks for providing the follow up 👍

I've also added the "prosemirror-transform" resolution inside this package in the hopes to prevent future reports until compatibility is achieved.
