---------------------------------------

             Summary: Hover indicator shows on incorrect row when scrolled and CollectionChangeEvent is dispatched
                 Key: FLEX-34190
                 URL: https://issues.apache.org/jira/browse/FLEX-34190
             Project: Apache Flex
          Issue Type: Bug
          Components: Spark: DataGrid, Spark: Scroller
    Affects Versions: Apache Flex 4.11.0
         Environment: Apache Flex 4.11 AIR 3.9, Desktop
            Reporter: Marcus Wilkinson


Steps to reproduce:
* Create and run the attached project.
* click on the "change something" button on one of the lower rows

Actual result:
* The row two or three higher than where the mouse is shows the hover indicator

Expected result:
* The hover indicator does not change from the row under the mouse


Culprit seems to be in spark.components.Grid.as, the function updateHoverForDataProviderChange computes the hoverRowIndex to be one which ignores the current scroll position.
