Poking at this a bit more -- the translation of these events apparently
relied on some magic in `read-event':
;; These translation functions actually call the focus handlers
;; internally and return an empty sequence, causing us to go on to
;; read the next event.
(define-key map "\e[I" #'xterm-translate-focus-in)
;; By returning an empty key sequence, these two functions perform the
;; moral equivalent of the kind of transparent event processing done
;; by read-event's handling of special-event-map, but inside
;; read-key-sequence (which can recognize multi-character terminal
;; notifications) instead of read-event (which can't).
(defun xterm-translate-focus-in (_prompt)
(setf (terminal-parameter nil 'tty-focus-state) 'focused)
(funcall after-focus-change-function)
[])
This works in Emacs 26.1, but not Emacs 27.1. I've stared at the
changes in read_key_sequence, but nothing seemed immediately suspicious
here...
