Since the build history was rewritten (https://github.com/jenkinsci/jenkins/pull/9148), while browsing some projects, the message "no builds" is displayed in the build history widget.

This is a bit confusing to users because in fact it is loading data and the message is replaced a short while after by the actual builds records.

I attached a short screen recording taken on https://ci.jenkins.io where the phenomenon can be observed. The actual delay depends on the server response time (which can be increased if it has to load some builds from disk).

A better experience would be show a specific message "Loading builds..." while the initial load happens.
