This rule was added in rubocop-capybara 2.19.0. We were following it
about 85% of the time.
Now we won't have to check both have_css and have_selector when
searching the code.
We weren't showing the details of answers without a description, even if
they had images, videos or documents. Some users found that behavior
unexpected since the description isn't a mandatory field and so they
left it blank, but they added images to that answer and they didn't
appear on the poll page.
Note we had a condition not to show the title of an answer when it had
no description. I think that condition was redundant because answers
without a description weren't loaded in the first place. Anyway, that
condition doesn't make sense anymore because we're displaying answers
with images but no description.
