bug#32607: 27.0.50; pop-to-buffer in next-error-no-select

> What is bad in user customization?

That this particular one

(setq display-buffer-alist '(("\\`\\*grep\\*\\'" display-buffer-same-window)))

apparently doesn't do what its writer intended.  This customization
means that its writer requests to display the buffer in the selected
window _regardless_ of whether the displayed buffer is already
displayed anywhere else.  Such a request is legitimate (think of the
case where I am perviewing a part of a buffer in another window and I
do not want to change that window's point) and an application should
not override it.  I think the intended customization in the case at
hand is

(setq display-buffer-alist '(("\\`\\*grep\\*\\'" (display-buffer-reuse-window 
display-buffer-same-window))))

Or what am I missing?
