I have AG-Grid with high frequency updates and I am using transaction api from AG-Grid.

Everything seems to work fine e.g. using keyboard to move cell and cell selection when clicking the cell both work fast. However, when I click a cell - the cell gets highlighted instantly but the row selection take a bit of time before it shows highlighted row.

In this link, if you see second example the row and cell selection is instant. I don't have much happening in the onCellClick event and I don't have CellSelection or RowSelection events wired up. The grid has around 50 rows and a lot of columns which are flashing but columns are virtualised.

Any idea why the selection of only row highlighting take longer whereas the cell is highlighted instantly ?
