| 133 |
// cross-origin iframes, and same-origin WP pages embedded as iframes. |
| 134 |
// |
| 135 |
// ROOT CAUSE: a same-origin WP page loaded inside an <iframe> has its |
| 136 |
// OWN copy of client_main[.min].js running. That copy calls |
| 137 |
// darkify_check_preloading() → localStorage.darkify_last_state="1" → |
| 138 |
// adds darkify_dark_mode_enabled to the iframe's <html> → goes dark. |
| 139 |
// The parent's darkify_process_iframes guard is irrelevant here. |
| 140 |
// |
| 141 |
// Stage 1 — 'before' (runs BEFORE client_main[.min].js on EVERY page): |
| 142 |
// If this page is rendering inside a frontend iframe, intercept the |
| 143 |
// localStorage.darkify_last_state property via Object.defineProperty so |
| 144 |
// that darkify_check_preloading() always reads "0" and returns false. |
| 145 |
// This prevents the iframe page's own Darkify from initialising dark |
| 146 |
// mode at all — works with both source and minified JS because |
| 147 |
// darkify_check_preloading() always reads the property directly. |
| 148 |
// The source JS also has a _dkf_iframe_disabled guard for belt-and- |
| 149 |
// suspenders coverage. |
| 150 |
// |
| 151 |
// Stage 2 — 'after' (runs AFTER client_main[.min].js on EVERY page): |
| 152 |
// • Cleans up the localStorage property intercept from Stage 1. |
| 153 |
// • Overrides the five injection helpers so the PARENT page's |
| 154 |
// darkify_apply_dark_to_iframe() applyDirect() closures (which look |
| 155 |
// up these functions by name in the global scope at call time) become |
