Ambari UI gets into corrupt state after installing a cluster

Steps to reproduce:

• Install a cluster via Ambari UI

• In the "Customize Services" step open the "All Configurations" tab and view the main configuration page for a service. I checked it with HDFS and HIVE.

• Continue installing the cluster.

• When done, select the service of which you viewed the configs during installation and check the configs.

• Configuration page will be corrupt. See screenshots below. It will go back to normal after reloading Ambari UI in the browser.
