What's Wrong?

When both the first line of the status line and the Context low (8% remaining) ... message appear, and the terminal is not wide enough to fit them all, lines after the first line are truncated as well.

What Should Happen?

Regardless of how the first line display is modified, lines after it should be displayed without any issue.
