[bug] TFJob dashboard UI not showing up through Ambassador reverse proxy

[swiftdiaries]

Is this a BUG REPORT or FEATURE REQUEST?:

/kind bug

What happened:

Tried the ambassador reverse proxy to connect to the TFJob dashboard. Got an empty page.

What you expected to happen:

Wanted the TFJob dashboard. Shown below.

How to reproduce it (as minimally and precisely as possible):

ks init my-kubeflow
cd my-kubeflow
ks registry add kubeflow github.com/kubeflow/kubeflow/tree/master/kubeflow
ks pkg install kubeflow/core
ks pkg install kubeflow/tf-job
NAMESPACE=kubeflow
kubectl create namespace ${NAMESPACE}
ks generate core kubeflow-core --name=kubeflow-core --namespace=${NAMESPACE}
ks param set kubeflow-core cloud gke --env=cloud
KF_ENV=cloud
ks apply ${KF_ENV} -c kubeflow-core
PORT=4004
PODNAME=`kubectl get pods --namespace ${NAMESPACE} --selector="service=ambassador" -o \
jsonpath='{.items[0].metadata.name}'`
kubectl port-forward --namespace=${NAMESPACE} $PODNAME ${PORT}:80

Then open http://127.0.0.1:4004/tfjobs/ui/ in your browser.

Is this the same problem as kubeflow/trainer#323
