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 mermaid-js/mermaid#1257.
