When Agenda buffer is in a side window, several actions fail with
"Cannot make side window the only window".
Example:
emacs -Q
in *scratch*, (setq display-buffer-alist '(("\\*Org Agenda\\*"
display-buffer-in-side-window)))
M-x org-agenda t to display Todo agenda
in org-agenda buffer, another M-x org-agenda is observed fails with error above,
expected is display the menu to select agenda command
Other failing commands are for example changes of todo state in agenda
buffer.
The reason seems that org-agenda-get-restriction-and-command calls
delete-other-window; however, this is not something user observes and
expects as effect of those commands.
Observed on Org 9.6 as well.
