I’m trying to make a custom node view which has a non-trivial structure and `contentDOM` is not a direct descendant of the `dom`.

```auto
list_item: () => {
  let dom = document.createElement("li");
  let contentDOM = document.createElement("div");     
  dom.innerHTML = `<span>prefix: </span><div class="inner"></div>`;
  dom.querySelector(".inner").appendChild(contentDOM);
  return { dom, contentDOM };
}

```

The `Enter` is set to split the list item and `Shift+Enter` is set to split the paragraphs inside the list item.

**The problem** is when I do `Backspace` on a 2nd empty line:

Instead of putting a cursor at the end of the first line it removes all lines from a list item.

I suspect the parsing of DOM isn’t set correctly but I can’t figure out how to do that — the callbacks in a parsing rule for `list_item` don’t get called at all (see `console.log(...)` there).

Added some `console.log` inside PM:

- Seems like `contentElement` isn’t get called if `getContent` is set.
- `getContent` is set by PM itself on rule (and overrides the one provided by me) if `contentLost` is `true`

But I can’t figure out how `contentLost` become `true` in my case — seems like `contentDOM` element is being detached from `dom` element at some point.
