Atomic will not resolve the issue

Example chart: https://github.com/distorhead/ex-helm-upgrade-failure

1. Check out master, run deploy.

git clone https://github.com/distorhead/ex-helm-upgrade-failure
cd ex-helm-upgrade-failure
helm upgrade --atomic --install --namespace myns myrelease .

Chart contains 2 deployments -- myserver1 and myserver2:

Release "myrelease" does not exist. Installing it now.
NAME:   myrelease
LAST DEPLOYED: Tue Feb  5 23:48:57 2019
NAMESPACE: myns
STATUS: DEPLOYED

RESOURCES:
==> v1beta1/Deployment
NAME       READY  UP-TO-DATE  AVAILABLE  AGE
myserver1  1/1    1           1          5s
myserver2  1/1    1           1          5s

2. Make breaking change. Delete deployment myserver1 from chart and modify deployment myserver2 with user-error (delete image field for example):

git checkout break-atomic
git diff master

diff --git a/templates/deploy.yaml b/templates/deploy.yaml

3. Run deploy:

git checkout break-atomic
helm upgrade --atomic --install --namespace myns myrelease .

Say hello to our friend again:
