Show all image sizes in Gutenberg (MediaUpload) [WordPress]

For me, they were gone overnight ...

My last blog post has been delayed a bit because since the last update of WordPress (5.2.2), the thumbnail sizes I created were no longer loaded when I selected a picture with the MediaUpload component.

The problem

In one of my self-programmed blocks, I have had the function of going through every thumbnail size and continuing to use it accordingly.

['uhd','wqhd','fhd'].forEach(function (size){
	if (media.sizes.hasOwnProperty(size)) {
		image[size+'-url'] = media.sizes[size].url;
		image[size+'-width'] = media.sizes[size].width;
		image[size+'-height'] = media.sizes[size].height;
	}
});

However, when I wrote my last post I realized that the sizes I had created were not returned to my Gutenberg editor.

This had led to the cause that the original pictures were loaded and the pictures I upload are partially over 10mb in size.

The solution

Luckily I found a quick solution and was able to implement it directly. For whatever reason, this problem was solved by declaring my thumbnail sizes with the action image_size_names_choose.

function wpse_setup_theme() {
	add_theme_support( 'post-thumbnails');
	add_image_size( 'full-hd', 1920, 1080, array('center') );
	add_image_size( 'uhd' , 3840, 2160, array('center'));
	add_image_size( 'wqhd' , 2560, 1440, array('center'));
	add_image_size( 'fhd' , 1920, 1080, array('center'));
	add_image_size( 'xga' , 1024, 768, array('center'));
	add_image_size( 'vga' , 640, 480, array('center'));
	add_image_size( 'qvga' , 320, 240, array('center'));
}
add_action( 'after_setup_theme', 'wpse_setup_theme' );


function my_custom_sizes( $sizes ) {
	return array_merge( $sizes, array(
		'full-hd' => 'full-hd',
		'uhd' => 'uhd',
		'wqhd' => 'wqhd',
		'fhd' => 'fhd',
		'xga' => 'xga',
		'vga' => 'vga',
		'qvga' => 'qvga',
	) );
}
add_filter( 'image_size_names_choose', 'my_custom_sizes' );

In the official documentation of WordPress it is said that this function is to make the set thumbnail sizes, human readable, that is, if you have a product_spotlight size, for example, you can write: Image displayed at recommended products.

Conclusion

Since you do not need any names in the programming, which must be readable by a human, I strongly assume that this is a careless mistake.

Hopefully, the WordPress core team will fix this problem as quickly as possible so that WordPress users who have no programming skills will not face any problems.
