not folded completely in markdown with list points

Set folding level to `1`. With a markdown file like this:
```
# heading a
* list item 1
  something

# heading b
* list item 2
  something in this list
```

place the cursor is at `heading b`, then reload window, then the file opens with `heading a` folded, but `heading b` with `list item 2` showing, but not the `something in this list` (the list itself is folded).
