At the bottom of your Assistant query, the 'references' section appears to be collapsed at four or more entries, even in the desktop view.
Practically with every question, I always take a look at the sources first, and each time expand them manually:

Each reference takes around as much screen space as a line of text.
If needed, add a new option to Kagi settings, or remember the previous state (when expanded).
Desktop users who inspect the sources will likely welcome this feature.
