	/**
	 * Container of Parallax Backgrounds element that automatically checks for state enable status.
	 *
	 * Gets the background style and enable status based on the provided arguments.
	 *
	 * This function iterates through all the breakpoints and states in the provided `$args['backgroundAttr']` array
	 * and finds the first attribute with a non-empty `style` value and `enabled` set to `'on'`.
	 *
	 * This function is equivalent of JS function:
	 * {@link /api/js/divi-module/functions/BackgroundComponentParallaxContainer BackgroundComponentParallaxContainer} in
	 * `@divi/module` package.
	 *
	 * @since ??
	 *
	 * @param array $args {
	 *     An array of arguments.
	 *
	 *     @type array  $backgroundAttr  The background attributes for different breakpoints and states.
	 *     @type string $moduleId        The module ID.
	 *     @type int    $storeInstance   Optional. The ID of instance where this block stored in BlockParserStore.
	 *                                   Default `null`.
	 * }
	 *
	 * @return string The container component.
	 *
	 * @example:
	 * ```php
	 * $args = [
	 *     'backgroundAttr' => [
	 *         'desktop' => [
	 *             'normal' => [
	 *                 'mask' => [
	 *                     'style'   => 'background-color: red;',
	 *                     'enabled' => 'on',
	 *                 ],
	 *             ],
	 *         ],
	 *         'mobile'  => [
	 *             'hover' => [
	 *                 'mask' => [
	 *                     'style'   => 'background-color: blue;',
	 *                     'enabled' => 'on',
	 *                 ],
	 *             ],
	 *         ],
	 *     ],
	 *     'moduleId' => 'module1',
	 *     'storeInstance' => 1,
	 * ];
	 * $result = BackgroundComponentMask::container( $args );
	 *
	 * // This example demonstrates how to use the `container()` function to retrieve the background style and enable status.
	 * // It uses an array with two breakpoints ('desktop' and 'mobile') and two states ('normal' and 'hover').
	 * // The function will return the background style and enable status for the attribute with a non-empty `style` value and `enabled` set to 'on'.
	 * // In this case, the resulting style will be 'background-color: red;' and the enable status will be 'on'.
	 * ```
	 *
	 * @example:
	 * ```php
	 * $args = [
	 *     'backgroundAttr' => [
	 *         'tablet' => [
	 *             'normal' => [
