Invalid themes requests should redirect/404

[jonoaldersonwp]

A request to ​https://wordpress.org/themes/?p=5 returns a 404 error, but, then the JS kicks in and returns the themes front page.

This is incredibly messy from an SEO and from an analytics perspective.

We either need to:

• Continue to let 404 these 'properly' server-side, but replicate this experience client-side (which is odd, as adding an arbitrary query parameter like this shouldn't result in a 404), or;
• Ensure that the server-side request matches the client-side experience.

I can't reproduce this, is it still an issue? It may have been fixed by something else.

Wooho!
