Utilisateur:Tenbergen/mermaid ER Diagram attributes not shown

This is an example for Issue report https://github.com/SemanticMediaWiki/Mermaid/issues/78 .

The following sample code is taken straight from https://mermaid-js.github.io/mermaid/#/entityRelationshipDiagram . It should list attributes, such as "make" under "CAR", but it only shows the entity boxes.
