syntag highlighting requires flowchart to have an id/name behind.
So now when I remove the name/id it works in mermaid.live/edit and vscode preview but not syntax highlight, and when I add it it works in the syntax highlight in vs code but not the others.

Error is:
Lexical error on line 1. Unrecognized text.
