Can't configure a newly created categorized view

It just hangs on the request. I don't see anything showing up in the logs. Tried several browsers to make sure it isn't a browser issue.

Start by reproducing the configuration request for a newly created Categorized Jobs View, using the browser-independent behavior described in the issue. Inspect why the request hangs despite producing no logs, then verify that the view can be configured successfully and that the failure is covered by an appropriate regression check.
