[BUG] Fenced multiline code blocks inside lists are broken after switching to CodeMirror back and forth: {"type":"code","name":"N/A"}

Describe the bug

When using fenced code blocks with tripple backtick inside a list item, switching back and forth to CodeMirror breaks the structure, resulting in an error:

Parsing of the following markdown structure failed: {"type":"code","name":"N/A"}.
You can fix the errors in source mode and switch to rich text mode when you are ready.

It's not the same as https://github.com/mdx-editor/editor/issues/370, because code block language is set, but indentation and change of structure breaks it.

To Reproduce

Steps to reproduce the behavior:

1. Go to https://mdxeditor.dev/editor/demo

2. Switch to CodeMirror

3. Replace the code content with the following Markdown:

   * List item one
       ```tsx
       line one
       line two
       ```
   * List item two
   

4. Switch to MDX - for now everything is looking good

5. Switch back to CodeMirror - it will show something like:

    * List item one```tsx
    line one
    line two
    ```
    * List item two
   

   Note, the line break and indentation before the fenced code block start got removed

6. Now add anything else, e.g. another list item:

   * List item one```tsx
   line one
   line two
   ```
   * List item two
   * List item three
   

7. Switch back to MDX and see the error:

Parsing of the following markdown structure failed: {"type":"code","name":"N/A"}.
You can fix the errors in source mode and switch to rich text mode when you are ready.

As a result, if you try to edit a markdown document like installation instructions with a step-by-step instructions (lists) with fenced code blocks inside those lists, you'd have to manually add the linebreak before the fence ``` and indent the line for each such code block after each edit, which is quite tiresome.

Expected behavior

1. line break and indentation before the fenced block is not removed when switching back-and-forth to CodeMirror
2. code blocks are not broken
