Describe the bug
When I want to use comments providers, such as giscus, the page is not behaving as what I think. I can only see a "LEAVE A COMMENT" label at the bottom of the blog posts but no actual widgets.

To Reproduce
Follow the tutorial by Lazy Ren

Debugging
I believe the problem is that the _layouts/default.html doesn't include the /comments-providers/scripts.html.
I added {% include comments-providers/scripts.html %} to _includes/scripts.html and the problem is solved.
Is this a bug? If so I hope you could add the line to the file to solve this problem for others.
