Describe the Bug

I am trying to use the AstroAsides integration from the docs in my own site.

The integration works flawlessly in normal .md pages, but for .mdx pages, the directives get replaced by the correct code but the Aside component isnt being rendered.

This is the code for the integration https://github.com/withastro/docs/blob/main/integrations/astro-asides.ts

And the .mdx page returns the following html for the aside
