Error when rendering

[sebitacio]

I am using Markdown Extended extension to add block syntax, but when i have Markdown Preview Mermaid Support active, i get a syntax error. This is what a have.

::: alert-warning
*here be dragons*
:::

::: mermaid
sequenceDiagram
  A-->B: Works!
:::

And this is the result.

But when i disable it, the first part works fine.

Thanks.
