Unfortuately, this is the expected behaviour.  See
<http://doc.bazaar-vcs.org/latest/en/user-guide/index.html#pseudo-merging> for
example.

If you are “cherrypicking” just some revisions rather than merging a complete
branch, then it will essentially be recorded as a patch with no revision
history, as you've seen.  We plan to improve this, but we haven't got there yet.
