bug#65744: 30.0.50; [TRAMP] sudo:: opens /root instead of /

[German Pacenza]

Hi, since commit 5c101b1adac2b4f3cc4e08a6492b406952c529f3 tramp opens
"/root" instead of "/"

emacs -Q:
C-x C-f /sudo::/<TAB>
In the minibuffer the last "/" is replaced with "./"

So, to access / I need to enter "/sudo::/../"
