Description

$scope.gridApi.infiniteScroll.saveScrollPercentage(); $scope.gridOptions.data = $scope.gridOptions.data.concat(data); $scope.gridApi.infiniteScroll.dataLoaded();

After this code is used the grid loads the new data and keeps the position for the most part but actually jumps the top row down about 7 rows. Is this a bug? Or am I doing something wrong? Thanks.

Research direction
Investigate the infinite scroll implementation in ui grid, focusing on the `saveScrollPercentage` and `dataLoaded` methods in `$scope.gridApi.infiniteScroll`. Check how the scroll position is recalculated after new data is concatenated. Look at the grid's virtual scrolling and row height calculations.
