What configs can not be configured in the fontmatter config?

The docs states that the entire Mermaid configuration can be overridden by the diagrams frontmatter, except for the secure configurations. Which configurations are secure and not supported? I found that maxEdges and maxTextSize don't seem to work in the frontmatter configuration.

    maxTextSize: 10
