bug#52491: 28.0.90; Regression in window deletion with minibuffer

I would need a precise recipe with Emacs -Q to look into this.  I never
use *grep* buffers and when trying it in a one-window frame showing
*grep*, it pops up a new window for the first occurrence, reuses that
window for further occurrences and deletes that window when invoking
'quit-window'.
