title: Capybara click_link sometimes doesn't work
body: <p>I'm using Capybara 1.0.0 with default configuration.</p>
  
  <p>click_link "some existing text"  # --sometimes-- doesn't work. weird.</p>
  
  <p>find_link "some existing text"  # always works</p>
  
  <p>This may be a timing problem; or maybe not because find_link works brilliantly ok.</p>
  
  <p>I've checked the produced output file via save_and_open_page, it's ok too. Also, I've increased the wait time etc. But, neither did help.</p>
  
  <p>Before I goto the source of Capybara completely. What do you think that is gone wrong?</p>
  
  <p>Regards</p>
