It looks like you have 'ls' set to some alias and fish is outputting its
definition?  Perhaps comint-process-echoes doesn't apply because it's
not an exact echo?  See also
https://github.com/fish-shell/fish-shell/issues/1913.

        (when (and comint-process-echoes (not artificial))
          ...
            (if (and
                 (<= (+ comint-last-input-end echo-len)
                     (point-max))
                 (zerop
                  (compare-buffer-substrings
                   nil comint-last-input-start comint-last-input-end
                   nil comint-last-input-end
                   (+ comint-last-input-end echo-len))))
