Since upgrading to the current Orion, my tabs are showing the primary domain favicons, not those for the subdomain of the tab. This is especially obvious because I have mail.google.com, calendar.google.com, and messages.google.com next to each other.
Also, my kite.kagi.com tab is showing the main Kagi icon, not the Kite icon.

This is most obvious for these pinned tabs, but I have at least one unpinned tab showing the same behavior.
Tabs should show the favicon of the narrowest subdomain, so I can tell them apart.
