Describe the bug

If I try to add a wrong mermaid diagram in the markdown, an error appears in a div outside the markdown editor

Expected behavior

If the mermaid diagrams are wrong, then it should display the error in a proper way, or even do not display an error at all

Minimal reproducible example

1. Go to https://addonsv24.flowingcode.com/markdown-editor/editor-demo
2. Put the following text in the editor:

```mermaid
sequenceDiagram
Alice->>John: Hello John, how are you?
loop Healthcheck
    John->>John: Fight against hypochondria
end
Note right of John: Rational thoughts!
John-->>Alice: Great!
John->>Bob: How about you?
Bob-adsf>John: Jolly good!

3. The following error appear after the editor:
