Description
Prettier 3.6.2
Playground link
--parser markdown
Input:
- [ ] Foo
<!--
Something
-->
Output:
- [ ] Foo
<!--
Something
-->
Second Output:
- [ ] Foo
<!--
Something
-->
Expected output:
- [ ] Foo
<!--
Something
-->
Why?
I think that one makes more sense as it hangs off the list item

Trace the Markdown formatter behavior for descendant comments, then add regression coverage showing that formatting the input repeatedly preserves the expected indented output.
