[QA] Browser testing components that disappear quickly e.g. ajax

[Jon Robson]

It doesn't seem to work for my use case...

When I try:
Then(/^I see an upload progress bar$/) do
  on(ArticlePage) do |page|
    page.progress_header_element.when_present
    page.progress_header_element.when_not_present(20)
  end
end

I see:
    Then I see an upload progress bar                  #
features/step_definitions/uploads_steps.rb:60
      timed out after 5 seconds, waiting for {:class=>"uploading",
:tag_name=>"h2"} to become present (Watir::Wait::TimeoutError)
      ./features/step_definitions/uploads_steps.rb:62:in `block (2
levels) in <top (required)>'
      ./features/step_definitions/uploads_steps.rb:61:in `/^I see an
upload progress bar$/'
      features/uploads_page.feature:10:in `Then I see an upload progress bar'

It really is a case of blink and you miss it...
