sdk commit: RallySoftware/appsdk@4db0e5140f1c8acde96e424aa3fc9991d1734759
author: Mike Holm and Eli Soman
message: S78551: Fix whitespace issues in the Iteration Status page - replaced getFirstVisibleRowIndex and getLastVisibleRowIndex with non-recursive calculation - fixed paging bug where scrolling down does not get next rows in buffer - removing child pager rows before collapsing rows - collapsing last row will leave white space behind which was done purposefully to keep the cursor above the row being collapsed
