bug#54389: 27.1; orgalist freezes emacs on orgalist-insert-item after sublists

Hello,

I just froze my emacs with the help of orgalist:

1. Install markdown-mode and orgalist from (m)elpa
2. Open the following markdown content in a markdown buffer:

```

- Some text:
    - Item 1
  Press M-RET (orgalist-insert-item) here >
```

3. Go to the ">" character and press M-RET (which should be mapped to
orgalist-insert-item).
4. Emacs freezes and must be killed from another process.

This happens with orgalist 1.13 and markdown-mode 20220212.728.
