Changing featured image causes only one image show in media modal (using Classic Editor)

Changing featured image causes only one image show in media modal (using Classic Editor). This problem appeard in WP ver. 5.8 and is caused by infinite scroll setting. When using infinite scroll (is on) media modal shows all images, but when infinite scroll is off, then only one image shows when trying to change featured image. When featured image is set for the first time all images show in media modal (even in infinite scroll is off). My current workaround for this bug is to force load more images on initialization:

if( ! wp.media.view.settings.infiniteScrolling ) {
	wp.media.controller.FeaturedImage = wp.media.controller.FeaturedImage.extend( {
		initialize : function() {
			wp.media.controller.FeaturedImage.__super__.initialize.apply(this);
			this.get("library").more();
		}
	});
}

Infinite scroll is off and featured image is set for the first time.

Infinite scroll is off and trying to chnage featured image

I forgot to write that after selecting featured image for the first time post has to be saved (page reload is necessary) to see this bug.
