Hello, this is a feature introduced in a newer version of mermaid.

Unfortunately, updating to the latest version of mermaid is not an easy task because mermaid has done a major change in its API, incompatible with the way this plugin works.

I have made a hackish version here if you really need this feature: https://github.com/rpeyron/drawio_mermaid_plugin/releases/tag/0.1.5-mermaid11.3
