Steps to reproduce

  1. Open Sandbox Vault
  2. Create a nested list with a structure like this:
- A
	- A1
		- A1.1
		- A1.2
		- A1.3
			- A1.3.1
- B
  1. In Reading Mode, fold “List A1” by clicking its folding arrow
  2. Switch to Live Preview or Source Mode

Expected result

Only the children lists of “A1” get folded, like this:

- A
	> A1 ...
- B

Actual result

“List B” also gets folded into “A1” accidentally, like this:

- A
	> A1 ...

Additional information

I found the issue occurs when there is a gap in indentation levels between separate lists. In this case:

  • “List A1” (level 1) is followed directly by “List B” (level 0).
  • If I add another list with indentation level 1 called “List A2” above “List B”, like below, everything now folds correctly.
- A
	- A1
		- A1.1
		- A1.2
		- A1.3
			- A1.3.1
	- A2
- B
