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

 twig2

Example Code
