Screenshots or screen recordings

Mermaid version 10 brings in the new "mindmap" feature. As found in the review app, we can now create this!

As this is an MR on .com, which does not yet contain this update, we receive a render failure:

mindmap
  root((Top of Mind)) 
    branch1
        twig1
            leaf
        twig2
    branch2

Example Code

mindmap
  root((Top of Mind)) 
    branch1
        twig1
            leaf
        twig2
    branch2
