When I incell edit multiple rows I only receive a sync callback through `change` on the datasource for the last row with only that last row in the "changedItems". This results in the grid not removing the dirty indicator for any of the other rows, only the last one is removed. The rows are updated properly and I if I were to manually call grid.refresh() it removes the indicators. If I update the rows individually it has no problems.

Here I've updated only the first row:

Here I've updated only the second row:

Here I've updated the first 2 rows at the same time and only the last one is detected as updated:

Here I've updated the PRS column for all 4 rows to "5" and it saved correctly, but only the last row is detected as updated in the grid:

As there's a lot of code involved I can't just paste it here, I can provide snippets or information about particular settings though.
