Comment (by azaozz):

 Looking at this more: seems adding a trailing slash would make it work
 (somehow) for now. Not a fan of this solution but then there seems to be
 some "pretty unusual" code there (not really sure what is the intent for
 this use of substr_replace: `substr_replace( $script_path, '.asset.php', -
 strlen( '.js' ) )`, why the negative index and why do `strlen()` of a
 hard-coded string).

 Thinking the `trailingslashit()` would be better applied to
 `$template_path_norm` and `$template_path_norm`, not just when comparing
 the paths. Later on when construction the script/stylesheet URL
 `get_theme_file_uri()` removes slashes from the beginning of the fragment
 anyways.
