mermaid sequence diagram with autonumber hangs the task

Example diagram that hangs.

[mermaid]

sequenceDiagram autonumber Caller->>+Receiver: Receive call

Removing autonumber will lead to a successful build.

Actually, I think is an issue with mermaid-cli hanging. Still investigating.

No expert, but I suspect autonumber is not supported. The example works removing it and I found this on mermaid's repo https://github.com/mermaid-js/mermaid/issues/1257.
