 There's a small error in the `register_block_style_handle()` function
 which prevents us from properly determining if a stylesheet for a block
 exists or now.
 We use `$style_path_norm = wp_normalize_path( realpath( dirname(
 $metadata['file'] ) . '/' . $style_path ) );` to get the stylesheet's
 path, and then we check if the file exists by doing `$has_style_file =
 false !== $style_path_norm;`.
  The problem is that `realpath()` returns`false` if the file does not
 exist, however it then passes through `wp_normalize_path()` and the
 `false` value gets converted to an empty string.
