FLUID-4959: Added a height to the toggle label so it doesn't scale with the line spacing option. This will fix the 'off' text in position. Also added a fixed height to the fl-uiOptions container so that line spacing in UIO does not scale with UIO. This may not be a solution we want, but for the demo it helps keep UIO from looking broken.
