In IE when a window is small (horizontal scrollbar is displayed) click
or keyboard input on various parts of UI makes search tables scroll to
top. It prevents from selecting items in a table. This issue happens
when using absolute positioned element with overflow style. It's a bug
in IE.
Two workarounds were added to make UI usable in IE.
Adding position:relative; style to body element fixes the problem in
search pages. It doesn't help in association dialogs though.
The bug doesn't occur when some child element has focus. It's possible
to set focus to first visible checkbox while scrolling down but user
experience is very bad. Better solution seems to scroll back when IE
scrolls to top on mousedown. That way mouse click event happens on the
target element and it can gain focus and therefore be selected. Some
glitches still remains but is usable.
