When using the build name setter plugin to set build names to something more than #number, the build history in the left column will overlap the page content in many places, e.g. in job/<jobname>/configure.
The same thing happens on the 'project page' job/<jobname> if that has a bit of content (e.g with a long list of artefacts).
I've added a small screenshot.
I noticed the overlap depends on the witdh of the browser window (very narrow window: everything is ok because everything goes below the build history, very wide window: everything is ok because it fits, in between those 2 you can see the issue).
