gcloud init generates bad url with 279.0.0

I installed a fresh gcloud sdk (in Azure Cloud Shell if it matters...)

chad@Azure:~$ gcloud --version
Google Cloud SDK 279.0.0
bq 2.0.53
core 2020.01.31
gsutil 4.47

I'm trying to run 'gcloud init' -- but the URL it renders does not work...

chad@Azure:~$ gcloud init
