(Updated to commit 27ce6918390088fbd6f786fb1a856d740bcf57b0 to reproduce)
After switching to the new 2-column view in last weeks update long project/milestone names render off the page (and cause horizontal scrolling)
.element { white-space: normal; display: inline-block; }
Looks roughly right instead.. but is different styling than is normally used as these wrap in larger blocks of text. (And might not render right for all cases)
