TOC including doesn't work at the same level

[vsesh]

I have this file structure:

- toc.yaml
- toc_test.yaml 
- page1.md

toc.yaml:

title: test
items:
  - name: Test
    href: ./toc_test.yaml

toc_test.yaml:

items:
  - name: Test page
    href: ./page1.md

And I received this error in the end:

ERR Link is unreachable: ./page1.md in /toc_test.yaml

Everything works fine if you place sub_toc.yaml and page1.md in some subfolder.
