Quotes around font-family in sccs files makes svgs susceptible to line-wrap corruption

[ahl]

Is your feature request related to a problem? Please describe.
When used from https://github.com/asciidoctor/asciidoctor-diagram svgs generated by github.com/mermaid-js/mermaid-cli are line-wrapped which causes them to be corrupted. While clearly asciidoctor-diagram should not be doing this (asciidoctor/asciidoctor-diagram#308) I believe mermaid could make a simple fix to correct this.

Describe the solution you'd like
If the font-family were not surrounded by quotes (") line wrapping in the middle of the name of the default font family (trebuchet ms) seems to be processed fine. I'd propose that themes' sccs files drop the quotes.

Describe alternatives you've considered
Fix asciidoctor-diagram. In the interim, specifying a mermaid config file like this causes the quotes to be dropped:

{
  "fontFamily": "trebuchet ms"
}

Additional context
