Formatting of mixed checklists and bulletpoints is non intuitive

[AJamesPhillips]

Describe the bug

When mixing checklists and bullet points the whitespace needed to get the correct formatting is strange and non-intuitive

To Reproduce

Steps to reproduce the behavior:

1. Create a component (node)
2. Enter the following text in the description:

   [x] ABC
   * 123
   * 456
   [x] DEF
   [ ] 789
   [ ] 101
   [ ] 112
   [ ] GHI

3. In presenting mode this text is rendered as:

Expected behavior

The following rendered format is expected:

It it possible to achieve this by adding whitespace (see below for example text) but this is not intuitive:

[x] ABC
  * 123
  * 456

[x] DEF
- [ ] 789
  [ ] 101
  [ ] 112

[ ] GHI

It would also be preferable to have the indented checklists without needing to add the extraneous bulletpoint.
