There is at least another broken use case, reported on the Tramp mailing
list:

3) Open a buffer dedicated to a remote host, for example "C-x f
   /scp:host:". Start `shell', it runs on the remote host. Goto a
   directory which does exist on the remote host, but not on the local
   one, for example "cd /sh <TAB>". It does not expand to "/share" as
   expected, instead it tries to complete the filename on the local host.

This did work before.
