  // destination site.
  // For first, we try to determine which properties should be enabled (and
  // thus accessible and editable on UI) based on the source media image
  // entities' alt and title fields' content. We assume that if there is at
  // least a single value for an image's title property in the source
  // database, then we have to change visibility of the title property to
  // TRUE, so that it can be edited on the destination site as well.

  // the alt or title properties shouldn't be necessarily shown (and be
  // editable) on the entity edit form based on the source media entity's
  // alt or title field value, we still have to check the configuration of
  // the source site's image fields.
  // If any of the preexisting image field was configured to show the alt or
  // the title property, then we will make their input field visible.
