Describe the Bug

We need to use a symlink in content/docs that points to another folder higher up to make contribution of guides in our open source project (RIOT OS) more accessible.
We need a symlink so that we can still have the remark and rehype plugins that are applied by starlight and only work with files from the content/docs folder.

We found a strange impact on rendering of :::note annotations with .mdx files when they come from the symlink. Even more strange is that this works for normal .md files. Only .mdx files are affected.

Background

Normally in .mdx files I can write this:

:::note
This is a note
:::

and it renders as this:

But in a .mdx file that comes from a symlink this is ignored and the text is just printed normally without formatting.
