Mermaid doesn't delete nodes when called multiple times

[ghost]

Codes used (Typescript, just change let by var):

  let holder = document.getElementById('mermaidHolder');
  while (holder.firstChild) {
    holder.removeChild(holder.firstChild);
  }
  
  let node = document.createElement('div');
  node.className = 'mermaid';
  node.appendChild(document.createTextNode('My mermaid string'));
  holder.appendChild(node);
  mermaid.init();

When you call that the first time, all goes well.

If you don't change your mermaid string, all goes well.

But If you change your mermaid string, then the graph displays your older nodes, without the links.

If you change it again, the new nodes are appended to the existing ones.

If you change it again and take the first value back, then the nodes stay and the links are applied to your first value.

I'm sorry, it was a problem on my side.

I'm closing this, there's no error.
