Disable using EstimatedRowHeight for uneven rows with known heights #454
Description of Change
Modifies the ListViewRenderer and UnevenListViewDataSource to return an estimated row height of zero when the cell heights are known. This prevents iOS from attempting to use row height estimates unnecessarily, which causes scrolling issues (especially if the specified cell heights are very different from the minimum measured cell heights).
There are tests for both estimated row height and known row height, but they are not automated (nothing in the UI test platform for detecting this sort of thing).
