how to retain static properties on a layout component

[stefanprobst]

when wrapping a mdx document in a layout component via default export, how can i retain static properties defined on that layout component function?

example usecase: https://github.com/stefanprobst/issue-mdx-layout-props

in the above example, the mdx document default-exports a Layout component with a getPageWrapper property. how can i retain that getPageWrapper property on the default export after compilation (i.e. move it from MDXLayout to MDXContent)?

Why have this written in MDX though? Maybe this is distilled down, but it looks like only JavaScript, so why not have that in JavaScript?
