Remove trigger where scrolling viewport causes drop downs to close.   It interferes when a large popup causes the viewport to scroll (Select.html robot test) and is actually not necessary to fix the Dialog bug (refs #10547).   Fixes #11647 !strict.

Still leaves another failure on IE8 though, the last test in Select.html.   Problem is that clicking Select B while another Select A is open will close A but not open B.
