Commit 73b24b0ff0 for wordpress.org

commit 73b24b0ff0e7053211e901bd2166739ffc79e88f
Author: John Blackbourn <johnbillion@git.wordpress.org>

    Media: Account for boolean false being returned by `wp_getimagesize()` when dealing with potentially invalid images in `wp_read_image_metadata()`.

    Prior to PHP 8.5 a boolean value was silently ignored when being passed to `list()`, but in PHP 8.5 and higher this now triggers a PHP warning. This change adds an appropriate guard condition.
