Looking at the parameter output I saw that the file was being sent to the server, but not processed. In my config.ru file I had use Rack::RawUpload, :paths => ['/searches/upload']to setup the middleware, but running “rake middleware” didn’t show it as being active. It seems there are two ways to activate the middleware and I was using the one that requires the server to be started with the config.ru file. The Cucumber/Capybara/Selenium uses Webrick which doesn’t start that way. So I moved my middleware initialization into initializers/middleware.rb and now things are working nicely.
Qtlhighliter::Application.config.middleware.use(Rack::RawUpload, :paths => ['/searches/upload'])

built on the work of

and

$.fn.allMatchTallestHeight = function() {
  var max_height = 0;
  elements = $(this);
  elements.each( function() {
    if ($(this).height() > max_height) {
      max_height = $(this).height();
    }
  });
 
  elements.each( function() {
    $(this).height(max_height);
  });
}

So once you have that, you can then use it like this.

$(".cloud-box-content").allMatchTallestHeight();
