e.g. https://test.wikipedia.org/wiki/Draft:Foobar
The page curation toolbar is shown on the right (if not, click on "Curate this article" under "Tools" in the left-side navigation).
Only two buttons are available -- "Minimize" (works fine) and "Go to the next page in the queue". The latter goes to a page in the mainspace, not in the draftspace. That should be fixed, or we should hide the toolbar entirely in the draftspace.
In my opinion it's ideal to not only fix the "next page" button, but also allow some of the other tools like speedy deletion, since that applies to drafts.

When viewing drafts on testwiki, I also see a logged message in the JS console which I think is related:
```
Unable to parse stored filters: { "mode": "afc", "namespace":118, "afc_state":undefined, "showunreviewed":"1", "limit":20, "dir":"newestfirst" }
```
The `"afc_state":undefined` is probably breaking things, and is why you can't browse to the next draft (maybe).
