These expectations are already covered by attach_new_file, so they are no longer needed:
> expect(page).to have_css ".loading-bar.complete"
We can remove the tests:
> "Should update loading bar style after invalid file upload"
because the expectation:
> expect(page).to have_css ".loading-bar.errors"
It is already tested in "Should not update document cached_attachment field after invalid file upload"
