Changed URLs in image gallery after Update to 4.2.3

[La Geek]

After update from 4.2.2 to 4.2.3 images in gallery are not found anymore. If there is only one image, the popup works. I use the Magnific popup Javascript with the following code in functions.php:

/* Name: magnific_popup */

add_action( 'genesis_entry_content', 'dynamik_magnific_popup_hook_box', 10 );
function dynamik_magnific_popup_hook_box() {
	dynamik_magnific_popup_hook_box_content();
}

function dynamik_magnific_popup_hook_box_content() { ?>
<script>
jQuery(document).ready(function() {

	jQuery('.image-gallery').magnificPopup({
	delegate: 'a',
		type: 'image',
		closeOnContentClick: false,
		closeBtnInside: false,
		mainClass: 'mfp-with-zoom mfp-img-mobile',
		image: {
			verticalFit: true,
		},
		gallery: {
			enabled: true
		},
		zoom: {
			enabled: true,
			duration: 300, // don't foget to change the duration also in CSS
			opener: function(element) {
				return element.find('img');
			}
		}
		
	});
});
</script>
<?php
}

This worked fine over many WP versions. But now, after update to 4.2.3 the image urls have changed. Please hover the mouse over an image there:

Instead of image (popup) link

the link is now:

But if there is only 1 image in the gallery, the problem does not exist:

I tested this again on local environment. Changed nothing else, then uploading to 4.2.3. Before update all worked fine, after update the images have bad links.

PS: I can't choose below in dropdownmenu version 4.2.3 (only 4.2.2 or trunk), so I chosed 4.2.2, but it should be 4.2.3.

When I override the shortcodes.php of 4.2.3 with the shortcodes.php of 4.2.2 the problem is solved.

There are a lot of troubles with the shortcodes.php file, please see there:

Since I don't know, if the changes in includes/shortcodes.php are security fixes, I moved back to the file version 4.2.3. But hopefully a fix will be available soon.

And there is an official blog post about the issues:

@La Geek allowed me to take a look at the post content. It uses shortcodes all over the place and is similiar to the one reported in #33102. Closing as a duplicate.
