/**
 * @description
 * The `loadingContent` function returns a HTML string with the loading content.
 *
 * @param {object} options Loading content options.
 * @param {string} options.id Loading id.
 * @param {string} options.icon Loading icon. Written as markup on purpose, so the default SVG
 *   spinner (and any replacement for it) renders. Never pass a value derived from user input here.
 * @param {string} options.title Loading title. Escaped, so it renders as the text it is: markup
 *   passed here shows up literally instead of being interpreted.
 * @param {string} options.description Loading description. Escaped, like the title.
 *
 * @returns {string} HTML string with the loading content.
