I try to link from a subpage to a paragraph on my root index.md:

[MyLink](../index.md#contact)

This results when clicking in a 404 trying to open the following URL:

documentation#contact

Correct would be to link to

documentation/#contact (note the slash)

Just linking to the page itself works fine

[MyLink](../index.md)

documentation/ (slash is in the link)

Anybody has a clue if I do anything wrong or if this is a bug?

I use mkdocs with Materials template. Can provide more if required.
