Allow Codex Web to actually see the screenshots which it takes

Question

### What variant of Codex are you using?

Codex Web

### What feature would you like to see?

Clearly Codex Web doesn't actually see the screenshots which it takes (and I believe, cannot), since it frequently returns screenshots which show loading states or failed states without continuing to fix them. It would be really fantastic if Codex Web could just see it's own screenshots and fix those issues before outputting screenshots to the user.
