bug#43755: 27.1; Electric-buffer-list does not work with global-display-line-numbers-mode

[superdorodor3]

emacs -Q
M-x global-display-line-numbers-mode
M-x electric-buffer-list        (*scratch* buffer is focused)
n                                        (then, *Messages* buffer is focused)
RET

Expected behavior: Window switches to *Messages* buffer.
Actually what happens:  Window keeps displaying *scratch* buffer.

Best Regards,
Masa
