Moving up/down a folded checklist doesn't move its children along

[dandv]

Steps to reproduce

1. Paste the following Markdown in Editing mode:

- [ ] Todo item before
- [ ] Checklist
   - [ ] item 1
   - [ ] item 2
- [ ] Todo item after

2. Place the cursor on Checklist and Fold more (if Ctrl± doesn’t work in Vault, press Ctrl+P → Fold more).
3. On the folded Checklist, press Alt+Down

Did you follow the troubleshooting guide?

Yes. In the sanbox the Ctrl± and Alt+Up/Down shortcuts don’t work, but the bug can be reproduced via Ctrl+P commands.

Expected result

The entire folded Checklist should move after Todo item after. This is the case with any tree-oriented todo list application.

- [ ] Todo item before
- [ ] Todo item after
- [ ] Checklist
   - [ ] item 1
   - [ ] item 2

Actual result

Only the Checklist line is moved down.

- [ ] Todo item before
	- [ ] item 1
- [ ] Checklist
	- [ ] item 2
- [ ] Todo item after

Manage lists (bullet lists, numbered lists) like an outliner (Dynalist/Workflowy)

Over the years, obsidian has made progress in the management of lists (bullet lists, numbered lists) with the introduction of hotkeys to indent, move list items, and automatic reordering of numbered lists. However, Obsidian still handles each list items individually. It may be desirable that: when a list item is indented, all its subitems are indented as well; when a list item is moved, all its subitems are moved along with it. This is the behavior that characterizes “outliners” (like Dynal…
