<tlp-relative-date> is not supported on legacy browsers. This means that users using those browsers won't see any date displayed which may be problematic. While we cannot start to support those legacy browsers and should encourage users to upgrade, at the very least we have a way to reduce the friction by providing a fallback value for the component:
- If the browser cannot interpret the component, the fallback value will be displayed.
- Else the fallback value will be replaced by rich content, based on user preferences.
