[BUG] org-agenda-list opens new frame with org-agenda-window-setup other-window and split-window-vertically [9.6 (release_9.6-49-g47d129 @ /home/data1/protected/Programming/Software/emacs/lisp/org/)]

[Jean Louis <bugs@gnu.support>]

When I set following:
(setq org-agenda-window-setup 'other-window) with intention to get
agenda in other window, together with following:

(setq split-window-preferred-function 'split-window-vertically)

then

(org-agenda-list)

is not going to show itself in other window but in new or other frame.

Only when I leave following variable:

(setq split-window-preferred-function 'split-window-sensibly)

Then agenda would show in other window.

Expected action is not that agenda shows in other frame but in other
window no matter how split-window-preferred-function is set.
