Current behaviour

Create a note with the following Mermaid:

```mermaid
timeline
	section Line One <br> Line Two
		Step One: a
		Step Two: d

Expected behaviour

Per the mermaid documentation for 10.9.1, it should render with a forced line break between Line One and Line Two, as it does on mermaid.live.
