Add tests to cover bottom button functionality.

[demiankatz]

This contains tests originally included in #4211 but split off due to problems with Mink behavior.

I finally figured out a way to get the tests to consistently pass, but it's a very ugly hack: detect when the native Mink click has failed, and then try again using a jQuery click manually performed with Javascript.

I have absolutely no idea why this is necessary. Why are clicks failing to register only on bottom buttons? Why is it only 10% of the time (for the print test -- even less frequent for the bulk test)?

Do we want to merge this with the ugly hack included, or is there a better way?

I added this waitStatement to both of the tests so that they match other earlier tests with the same behavior. It was an early attempt to fix the click-non-registration problem. It didn't help. I'm not sure if we should leave this in or take it out.

I also did some more testing and think got closer to the reason.

I tried to include the bottom buttons in the form and also replaced them with the top buttons. This did not fix the problem. When I also moved the buttons above the results the problem did not occur anymore.

So I believe this has to do with the position on the page and if you have to scroll down.

I tried to resize headless browser with --window-size="1366,2000" without an influence.

After resizing the window with $session->resizeWindow(1280, 2000, 'current');, the test now failed even without headless mode.

For some reason I could completely fix the problem by setting the height of the window to either $session->resizeWindow(1280, 200, 'current'); or $session->resizeWindow(1280, 10000, 'current');.

Can you reproduce this behavior?

Thanks, @ThoWagen, I'm seeing exactly the same behavior. I have revised the test to use the window resize workaround instead of the Javascript workaround, and this feels slightly less awful than that (though it's still not at all a good thing, obviously!).
