BUG: ListGrid.refreshCell(rowNum, colNum) does not work properly

The methods ListGrid.refreshCell(rowNum, colNum) and ListGrid.refreshCellStyle(rowNum, colNum) refresh all the cells in the row rather than just the specific cell. Apart from this issue, I have observed that these methods also impact the functioning of methods like ListGrid.getEditedRecord(rowNum), ListGrid.getEditValues(rowNum), ListGrid.setEditPendingCSSText(String cssText).

Please look into this issue and suggest remedies/alternatives.
