Visit the pagure.io homepage without being logged in (or if logged in, hit Browse). Try to search for a project which doesn't exist, e.g. "findutils". Assume you're not intimately familiar with pagure's behaviour. Type quickly. Hit enter.

Actual result:
"findutils" appears in the search box. There is no other response. Hitting enter does nothing.

This has tripped me up a couple of times now. Clearly my forgetfulness makes me well-suited for UI testing :).

Minimally expected result:
If we maintain the current type-to-search with Enter selecting the first shown result, there should be a dummy "No results found" result when the search box is non-empty, but there are no matching projects.
