Home bookmark link is blank

Problem/Motivation

When the homepage is bookmarked, the Bookmarks view displays the homepage item, but the link is missing. Other pages, nodes, and views links were successfully displayed in the Bookmarks view.

Steps to reproduce

With a vanilla Drupal instance, logged in as administrator:

1. Acquire and enable the Bookmarks module.
2. Add the block placement.
3. Go to the homepage.
4. Add the homepage to favorites.
5. Edit to the Bookmarks view.
6. Add your user's id to the context filter and Update preview.

This was done with a vanilla Drupal instance where the homepage was still set to /node.
