NOTE: Adding the following code in your Plugin's boot() method will dump the CMS page event stack to your system.log file:

$events_history = [];
Event::listen('*', function ($event, $params) use (&$events_history) {
    if (!str_starts_with($event, 'cms.')) {
        return;
    }
    $events_history[] = $event;
    if ($event === 'cms.page.display') {
        trace_log($events_history);
    }
});
