Sometimes when I reference a file using @file it does not show any matches, and cannot find it when prompted to.

Even after searching for the name, it will sometimes fail.

What steps can reproduce the bug?

I'm not sure what triggers this.

What is the expected behavior?

It should have no problem finding the file, and it should show matches when @ is used.
