Description Ivan Furnadjiev CLA 2014-10-01 04:34:00 EDT 
Reproducible with all demos. In Examples Demo -> TableViewer page click on the empty space bellow the scrollbar thumb -> Table scrolls to the end. Before (RAP 2.3) it scrolled with one page.

We changed Grid scrolling to be based on items, not on pixels (support different item heights). Unfortunately, page increment calculation is still based on pixels (ScrollBar.js#_updatePageIncrement). As a result page increment is too big (in pixels) and always scrolls to begining/end.

... in server-side Nebula Grid implementation page increment is set to 1 in case of different item heights.
