This component relies on a depreciated class that we would like to get rid of, before we do so, we have to make sure this component will still render as expected.

It is especially important that we migrate this component so that it can benefit from the new updated stylings coming from GitLab-UI's new design tokens (https://design.gitlab.com/product-foundations/design-tokens/)
