It's this patch. It adds an invisible empty line at the beginning of
*Completions* when completions-header-format is not a string (in
particular, nil) or an empty string.

Subject: [PATCH] Fix handling of completions-header-format
* lisp/minibuffer.el (display-completion-list): Insert an
invisible line when completions-header-format is not a string (in
particular, nil) or is an empty string. Fixes bug#60411.
Also, do not use completions-header-format when it is not a
string.
