Problem
When viewing the logs for a run, a step with a very long string for description will truncate but not show the ellipsis.

There also seems to be some strange resizing behaviours https://cl.ly/291x3T3l0x11

Repro Steps

1. Create a multibranch project with a Jenkinsfile that has a very long step description, such as echo'ing a long string. Ex: https://github.com/histos/karaoke-samples/blob/step-description-long/Jenkinsfile
2. Let the job run
3. Open the run details

Expected Behavior
The step description should truncate and show an ellipsis.

Actual Behavior
The step description truncates but does not show an ellipsis.

Notes
The layout is flexbox based and there appear to be known issues with using flexbox along with white-space: nowrap. Check out the tables work being done by Josh should probably yield a basic CSS layout that should work.
