It looks like suppressing word-wrapping is itself being suppressed.
Note how in the element inspector, I see only my font-family style applied.

Tried various other style options to either suppress or alter word wrapping, but no luck. I can manually insert the style tag and see it update, but I can't seem to get this into the popup configuration itself.
Alternative: combine text-indent and margin-left? Then the new line is at least a bit clearer to users.
