Comment:

 Ran into an issue with this one. Dependency resolution takes place for all
 scripts in the header, and again in the footer. If you register a script
 to output in the footer, but it depends on something registered after
 `wp_head`, you get an error despite the script being output correctly.

 We need to take this into account when passing in `$handles` to
 `all_deps`; an `array_filter` should suffice.
