 /**
  * This component needs to ensure it didn't end up with empty content.
  * This will go through sanitize_text_field later as part of the assembled JSON.
  * Therefore, tags aren't valid but we need to catch them now
  * or we could encounter a parsing error when it's already too late.
  *
  * We also can't do this sooner, such as in build, because at that point
  * the component could still contain nested, valid tags.
  *
  * We don't want to modify the JSON since it will still undergo further processing.
  * We only want to check if, on its own, this component would end up empty.
  *
  * @access public
