Set the current buffer before handling key events

There's no guarantee that the global current buffer matches the selected
window's buffer. For example, the following  will output "*Messages*" regardless
of the actual current buffer:

  (progn
    (run-at "1 sec" nil (lambda ()
                          (with-current-buffer (get-buffer "*Messages*")
                            (sit-for 5))))
    (run-at "2 sec" nil (lambda () (message (buffer-name)))))

* exwm-input.el (exwm-input--on-KeyPress): Set the current buffer to selected
window's current buffer.
