title: Capybara HTML 'number' attribute interaction
body: <p>I'm testing a webpage that has two input fields of type <code>number</code>. When I hover over a field, two arrows, up and down, appear to increase or decrease the value in the field.</p>
  
  <p>Is there a Capybara script that would click these arrows?</p>
  
  <p>I can use a standard <code>fill_in</code> function to change the value, but I would like to automate clicking the arrows to change the value.</p>
