It's not a bug. Bash maintains a logical view of the file system and the
current directory for cd, pwd, and $PWD, as Posix specifies.  One of the
consequences is that the pathname of the current directory depends on the
path used to reach it, which affects how bash canonicalizes `..'. Bash is
consistent in  its use of this logical view across shell features, which
includes completion.

If you want to see a physical view of the file system, use
`set -o physical'.
