bug#47781: 28.0.50; (window-list-1 nil t) returns nil when minibuffer is inactive

[marmot-te]

Hi,

I read from the docstring of the function
> MINIBUF t means consider the minibuffer window even if the 
> minibuffer is not active

However, 
with emacs -Q
and the minibuffer inactive

(window-list-1 nil t)
;; => nil

I think this is related to this build since I cannot reproduce 
with emacs 26.1 (in this case it returns the list of windows, 
minibuffer included, as expected).
