 == Test Report

 Testing Environment:

 * Browser: Safari 15.4
 * Theme: Twenty Twenty-Two
 * Server: macOS 12.3, PHP 8.0.18 (native), Apache 2.4.53 (native)
 * WordPress: 6.0-alpha-52448-src


 TL;DR

 I can't reproduce this bug.
 The width of the image is limited by the value of the `$content_width`
 global variable.
 There is no bug in the `wp_get_attachment_image_src` function.
 More info can be found here: https://codex.wordpress.org/Content_Width

 == Steps to test

 1. Activate `Twenty Twenty-Two` theme.
 2. Go to the `src/wp-content/themes/twentytwentytwo/functions.php` file
 and add the following code to the very end of the file:

 {{{
 global $content_width;
 $content_width = 2000;
 add_action( 'after_setup_theme', function() {
         add_image_size( 'featured-home', 1600, 600, true );
 } );
 }}}

 3. Go to the Media Library and upload a test image that's exactly `1600` x
 `600` in size.
 4. Go to the database and check the last ID in the `posts` (`wp_posts`)
 table.
 5. Add the following code to the very end of the `src/wp-
 content/themes/twentytwentytwo/functions.php` file (don't forget to
 replace the ID):
 {{{
 $image = wp_get_attachment_image_src( 'replace this value with ID of the
 last post', 'featured-home' );
 }}}
 6. Check the contents of the `$image` array (either with
 [https://www.php.net/manual/en/function.print-r.php print_r] or XDebug).

 === Actual result:
 [[Image(https://cldup.com/_jxDZKLgee.png)]]
 === Expected result:
 It should return an image that is 1600 x 600 in size.
 That's exactly what's happening here, meaning there is no bug.
