Prettier 3.9.0 started adding blank lines around comments in Markdown lists #19510

Prettier v3.9.4
Playground link

--parser markdown

Input:

- Head
<!-- divider -->
- Body
<!-- divider -->
- Foot

Output:

- Head

<!-- divider -->

- Body

<!-- divider -->

- Foot

Expected output:

- Head
<!-- divider -->
- Body
<!-- divider -->
- Foot

Why?

It is not clear why empty lines are added around the comments. As far as I can see, this is not mentioned in the 3.9.0 release notes.
