Built-in mermaid override parent mermaid in jupyterlab

[microcoder]

Extension jupyterlab-myst and its built-in plugin mermaid override parent mermaid in jupyterlab v4.4.0a1 and above. How to disable old mermaid in MyST and use new mermaid v11.4.1 in jupyterlab without turning off jupyterlab-myst?
