#59896: Block editor default styles not loaded when stylesheet with the same name
as the theme is registered

 I've got a custom theme that lives in a directory called "coderpad".
 Inside the theme I load a custom stylesheet with the handle "coderpad"
 which is registered via the "init" hook and enqueued via the
 "wp_enqueue_scripts" hook. I don't load any sort of custom editor styles
 as part of this theme.

 After upgrading to WordPress 6.4 the block editor fails to load any
 default styles. The content in the editor looks like a big wall of text
 without any formatting. My simple workaround is to only register the
 stylesheet when it's not an admin request:


 {{{
 if ( ! is_admin() ) {
     wp_register_style(
         'coderpad',
         get_template_directory_uri() . '/assets/css/coderpad.min.css',
         array(),
         null,
         'all'
     );
 }
 }}}

 This issue also appears to not happen if I rename the stylesheet handle to
 something like "coderpad-foo"

 Here are two screenshots of what is happening: https://imgur.com/a/kgKkrmw

 I'm not sure if there is logic somewhere that detects if a stylesheet with
 the same handle as the theme directory is registered then don't load
 default styles but thought I would post about this unexpected behavior.
