Unable to use absolute path for coverpage, loadNavbar, or loadSidebar options #1407

Bug Report

Steps to reproduce

Set coverpage, loadNavbar, or loadSidebar options to an absolute URL and load site. For example:

coverpage: '/docs/_coverpage.md'

coverpage: 'http://domain.com/_coverpage.md'

What is current behaviour

Docisfy incorrectly assumes all URLs should be prepended with a forward slash resulting in the following:

• coverpage: '/docs/_coverpage.md' makes a request for //docs/_coverpage.md
• coverpage: 'http://domain.com/_coverpage.md' makes a request for /http://domain.com/_coverpage.md

For coverpage, I was able to identify the line causing the issue here:

What is the expected behaviour

Docsify should not assume all URLs should be prepended with a forward slash. More investigation is needed to determine why docsify is concatenating root + path in the source (see above).

Other relevant information

• Bug does still occur when all/other plugins are disabled?

• Docsify version: 4.11.6
