1/**
2 * @file
3 * Fixes DOMContentLoaded timing for JobSolutions iframe-embed.js after Klaro consent.
4 *
5 * Klaro blocks iframe-embed.js (from jobsolutions.be) until consent is given.
6 * When consent is granted and the script re-executes, its internal
7 * DOMContentLoaded promise never resolves because the event already fired.
8 * This loader patches document.addEventListener before Klaro re-enables the
9 * script, so the DOMContentLoaded listener fires immediately and
10 * iframe-embed.js can initialize the vacancy iframe properly.
