/**
 * Body video block.

 * Customizations:
 * - support external sources for preview image
 * - added ConditionalEmbed
 * - changed icon for preview with FontAwesome icon
 * - overhauled url checking, it would break on correct links and allow incorrect ones
 * - video passed to ConditionalEmbed only when cookie are accepted, preventing the fetch when not accepted
