Incorrect alignment of content nested below checkboxes

[wisp3rwind]

When nesting some content below a checkbox, (e.g. a a list or a longer descriptive text or a quote, cf. the screenshot below), I would expect them to be aligned with the first letter of the checkbox item (the b and c in the screenshot). Currently, Joplin renders them aligned with the checkbox itself such that the nesting cannot be discerned from the rendered output.
The expected output would be just like that for an actual list as shown in the bottom half of the screenshot.
