References to same page doesn't work

**Path to the page with the problem (_do not_ include domain name):**

**Describe the problem:**
This is a bug where the self-reference no longer works. Using just #name_mode is no longer working and affects other pages as well. This might be due to a version update. Not using # correctly constructs the link but that link will be broken because # is required.

**Screenshot, if possible**

**Describe how the site should look?**
Clicking the link above should move us to the source section of the current page. Instead it redirects us to homepage.

The issue does not name a file or page path. Start by reproducing a `#name_mode` link on an affected page and trace the site's link handling; done means clicking it reaches the source section on the current page instead of the homepage.
