        (font-size, font-family and line-height) as it is expected to be used
        within another component such as paragraph or caption. For a more
        realistic storybook example of this component see the Paragraph and
        Caption stories - this should be removed in
        https://github.com/bbc/psammead/issues/733

        Please note this an experimental example of inline link styled with
        text-decoration: underline instead of border-bottom: solid. The 1st
        paragraph is an example of inline link in a regular paragraph and the
        2nd example is an example of inline link within a Caption. This has only
        been implemented for this storybook example. This experiment is a part
        of this issue: https://github.com/bbc/psammead/issues/2706
