When you have a button containing only an icon (such as just displaying a magnifying glass to indicate the submit button for a search input), there's no alternate display for assistive devices. This can be accounted for by placing text within the <i>
tag, but Bootstrap does not currently visually hide text within an <i>
tag.

The first group of buttons shows what happens currently when text is placed inside an <i>
tag. The second group shows the display after the suggested change.
