   Testing the scrolling behaviour of elements when in a normal and transformed container.
   On the left is the normal container. On the right are containers containing transformed elements.
   To test this manually, click on the two select elements. The menu popup should
   appear directly over the element - the content should not move.<br>
   The third and fourth containers tests that scrollIntoView(false) works properly in the presence of a scaled element.  Because the element is at the bottom of the container, scrollIntoView should give the same result regardless of flag.
