[ISSUE] Checkboxes/checklists

[fetusfinn]

Hi, ive found an issue where if you create a checkbox/checklist, and add a newline between each element, then it causes all checkboxes under that section (header, or divided by html tags) to insert a newline right after the checkbox, causing the text for that list item to be on the line after the checkbox. It also breaks if there are multiple lists (under the same section), separated with a blank line between the lists.

examples

# this works
- [ ] this is a checkbox
    - this is a sub list
- [ ] this is another checkbox
- [ ] and another
    - [ ] but with a sub checkbox

# this breaks
- [ ] this is a checkbox
    - this is a sub list

- [ ] this is another checkbox

- [ ] and another
    - [ ] but with a sub checkbox

# this breaks
- [ ] this is a checkbox
    - this is a sub list
- [ ] this is another checkbox

- [ ] this is separate but under the same header
- [ ] this is another checkbox
- [ ] and another
    - [ ] but with a sub checkbox

this works

- [ ] this is a checkbox
    - this is a sub list
- [ ] this is another checkbox
- [ ] and another
    - [ ] but with a sub checkbox
