/**
* A utility function for userscripts that detects and handles AJAXed content.
*
* @example
* waitForKeyElements("div.comments", (element) => {
* element.innerHTML = "This text inserted by waitForKeyElements().";
* });
*
* waitForKeyElements(() => {
* const iframe = document.querySelector('iframe');
* if (iframe) {
* const iframeDoc = iframe.contentDocument || iframe.contentWindow.document;
* return iframeDoc.querySelectorAll("div.comments");
* }
* return null;
* }, callbackFunc);
*
* @param {(string|function)} selectorOrFunction - The selector string or function.
* @param {function} callback - The callback function; takes a single DOM element as parameter.
* If returns true, element will be processed again on subsequent iterations.
* @param {boolean} [waitOnce=true] - Whether to stop after the first elements are found.
* @param {number} [interval=300] - The time (ms) to wait between iterations.
* @param {number} [maxIntervals=-1] - The max number of intervals to run (negative number for unlimited).
