The Mermaid theme component does not seem to work once installed on my instance.

Do note that when checking the official post: [Discourse Mermaid](https://meta.discourse.org/t/discourse-mermaid/218242)

It points to this preview: [Discourse Mermaid example - general - Theme Creator](https://discourse.theme-creator.io/t/discourse-mermaid-example/1553?preview_theme_id=6048)

The preview does not work for me on Firefox and Brave so it seems the issue is not specific to my install.

Hello and welcome @fryorcraken 🙂

Let’s see if it we can repro here:

```mermaid
graph TD;
  A --> B;

```

Can you see the example above?

Hi @fryorcraken 👋 I could reproduce your issue on an earlier commit version but it should be working now - can you update your Discourse please?
