Unable to Style Sequence Diagram Title

[Maxence Guindon]

Description

When adding a title to a sequence diagram, I'm unable to modify the title font size. My current workaround is to use a Markdown title.

I have seen other graphs in Mermaid have attributes related to the title, like QuadrantChartConfig, but it is not yet available for the Sequence Diagram.

Steps to reproduce

1. Create a Sequence Diagram
2. Insert a title
3. Add participant and interaction until the title gets very tiny
