add support multiple lines in "summary" section

[duchenpaul]

Is your feature request related to a problem? Please describe.
The render engineer seems to ignore newline symbols such as, so they render as one paragraph:

  summary: "line 1\nline 2\nline 3\nline 4"

Describe the solution you'd like
Summary sections could be better as one paragraph, but I think it is good to leave it to the users, so I suggest the render engine doesn't ignore newline (\n), tab (\t), etc.

Describe alternatives you've considered
Use <br> instead

Additional context
no
