Graphviz's filled and color attributes doesn't work

Like

`digraph {
node [style=filled,color=white];
a -> b
}`

The result is:

On viz-js.com , it seems :


I know why!.
The mermaid we use is older version, it's css file 'mermaid.forest.css' override the node's style.

So, If we upgrade the mermeiad, we do not need the mermaid.forest.css file. So it is ok.

Like this:

Inspect the Mermaid integration and the mermaid.forest.css file mentioned in the issue, then reproduce the Graphviz example with filled and color attributes. Done means the rendered nodes honor those attributes without the stylesheet overriding them.
