Change past event views to reverse chronological order

past-event-reverse-order.php

<?php

// Changes past event views to reverse chronological order
function tribe_past_reverse_chronological ($post_object) {

	$past_ajax = (defined( 'DOING_AJAX' ) && DOING_AJAX && $_REQUEST['tribe_event_display'] === 'past') ? true : false;

	if(tribe_is_past() || $past_ajax) {
		$post_object = array_reverse($post_object);
	}

	return $post_object;
}
add_filter('the_posts', 'tribe_past_reverse_chronological', 100);

The code works, unless you go to the list of past events following the "past events” link from the list of future events:

• if you click on "past events", all past events are still sorted with the first on top.
• only after manually reloading the page, the events appear in the correct order.
