I could have a fundamental misunderstanding of how git cherry-pick and git cl issue work but I was confused when I accidentally uploaded a new cl to an old issue with the following workflow:

What steps will reproduce the problem?
(1) cherry-pick one issue (git fetch && git cherry-pick FETCH_HEAD)
(2) cherry-pick a second issue
(3) make some changes and add a new commit
(4) git cl issue
(says there's no associated issue number)
(4) git cl issue 0
removes a change-id
(5) git cl issue 0
no issue number
(6) git cl upload
(7) cl with all three commits gets uploaded to the first cherry-picked cl's issue # as an initial upload

Copy pasted from my terminal:
ashleymarie@ashleymarie01:~/chromium/src$ git cl issue
Issue number: None (None)
ashleymarie@ashleymarie01:~/chromium/src$ git cl issue 0
WARNING: The change patched into this branch has a Change-Id. Removing it.
Issue number: None (None)
ashleymarie@ashleymarie01:~/chromium/src$ git cl issue
Issue number: None (None)
ashleymarie@ashleymarie01:~/chromium/src$ git cl issue 0
Issue number: None (None)

What is the expected result?
git cl issue would list if a patched in change has a change-id
git cl issue 0 would clear all related issue #s
git cl upload after git cl issue 0 would upload to a new issue
