The job page and its child pages are overlapped by a queued build. The finished and running builds descriptions are set to 200px, and never overlap.
However, the HTML for the queued builds is very different:

using a float right for the stop button instead of a td, not have a div to include the parameters which are shown where the desc is on building/built runs.

We have used the simple theme plugin to add the following CSS to make it work for now:

#side-panel, #buildHistory, tr.build-row {
  word-wrap: break-word;
}

.build-row.transitive > td:nth-child(2) {
  max-width: 200px !important;
}

Major because it makes the configure page impossible to work on if there are queued builds and the text overlaps it.
