/**
 * This plugin registers the selector syntax `style()`.
 *
 * ```
 * div[class="my-div":style(this=display:block&rule[]=>.my-selector{display:table;width:100%;}&global[]=>.my-global-selector:has(.blocked-element){display:table;width:100%;})]
 * ```
 *
 * Parameters:
 *
 * - `[this]` (string): CSS rules applied to the blocked element
 * - `[applyUnblocked=false]` (boolean): If true, the styles will still be applied after unblocking the element
 * - `[rule]` (string[]): An array of CSS selectors and rules relative to the blocked element
 * - `[global]` (string[]): An array of CSS selectors and rules which will be applied to the whole document. Use ".blocked-element" to target the blocked element
 *
 * The above example will result in the following CSS which modifies the style of the blocked element:
 *
 * ```
 * <style>
 *   div[consent-required][consent-style-2]{display:block;}
 *   div[consent-required][consent-style-2]>.selector{display:table;width:100%;}
 *   .my-global-selector:has(div[consent-required][consent-style-2]){display:table;width:100%;}
 * </style>
 * ```
