Notes about capybara's examples which are failing for capyabara-zombie

Capybara Zombie

  1) Capybara::Driver::Zombie it should behave like driver with javascript support#drag_to should drag and drop an object
     Failure/Error: @driver.find('//div[contains(., "Dropped!")]').should_not be_empty
     expected empty? to return false, got true

          jQuery draggable.start and draggable.stop events are fired.

          jQuery('#drag').offset() is {top: NaN, left: NaN} <== JSDOM doesn't implement element position; I think jQuery cares about this...
            NB: env-js does not implement position either
            NB: it looks like html_unit does
            NB: droppable is not raising 'over': jquery.ui.droppable.js uses $.ui.intersect to test for intersection.

          If I specify :pageX and :pageY (10, 136), I see this error now:

  2) Capybara::Driver::Zombie it should behave like session with javascript support all JS specs Node#drag_to should drag and drop an object
     Failure/Error: @session.find('//div[contains(., "Dropped!")]').should_not be_nil
     Unable to find '//div[contains(., "Dropped!")]'
     
          IGNORE: SAME AS FAILURE #1




  3) Capybara::Driver::Zombie it should behave like session with javascript support all JS specs#wait_until should wait for block to return true
    Failure/Error: @session.evaluate_script('activeRequests == 1').should be_true
    expected false to be true

        This has something to do with script execution contexts

         - $('#waiter').change is fired.
         - setTimeout works
         - but @session.evaluate_script('activeRequests') is _always_ whatever value `activeRequests` is given on line 1 of test.js
        
        I believe this is the same as [issue #37](https://github.com/assaf/zombie/issues/issue/37)

I've just did a pull request which solves (2).

Nice, thanks!

(BTW, when I deleted #2, I renumbered them, so they match the output rake is giving)

This failure was occurring because jQuery expected the 'click' event to be fired when the checkbox's value was changed.
4) Capybara::Driver::Zombie it should behave like session with javascript support all JS specs#check should trigger associated events
Failure/Error: @session.should have_css('#checkbox_event_triggered');
