When I drag and drop a directory to Dired in Emacs 26.3, it copies the directory (and its contents) to the directory that Emacs is showing. This is like the behavior in MS Windows explorer. I don't like that!, at least not for Emacs.
I prefer the old behavior where dired will rather just list that directory in Dired.
Can anyone please tell me what to hack to get back that old behavior? (Google did not provide me an answer, alas.)
