I get the error shown below when using the new Mermaid shapes (see [Expanded Node Shapes in Mermaid Flowcharts](https://mermaid.js.org/syntax/flowchart.html#expanded-node-shapes-in-mermaid-flowcharts-v11-3-0)) in HackMD.  There are some public HackMD sites that encountered the same error. such as [site1](https://hackmd.io/@HnyvbQaQTkGVIsK25lfdmg/BkxCSQf72), [site2](https://hackmd.io/@NCUESA/BJtTTUH2R). Will HackMD support Mermaid v11.3.0 and above?
