Description

• Fixed an issue where update history in DataManger was missing when using the setRows API.
  • This issue was caused by two mistakes.
    1. To efficiently update the update history, when looking for consecutive row indices, we checked for consecutive using the object itself, not the rowIndex property of the IndexedRow object.
    2. When removing old update history using consecutive rowIndexes of the rows being updated, the starting index was set without considering the number of previously deleted elements, resulting in incorrectly deleting old update history.
