Comment (by teor):

 Does this issue happen with the default torrc file (without any
 ExcludeNodes entries)?

 It looks like Tor Browser could be fetching the favicon from two different
 isolation contexts. Isolation contexts are a feature where requests that
 happen from different pages or areas in the browser, get sent through
 different exits. This protects your privacy by isolating requests from
 different sites.

 I wonder if Tor Browser considers the tab favicon and some favicon
 embedded in the page (or elsewhere) as different contexts?
