Why does the last edited cell remains selected after editing if I use editOnFocus with cellNav

I am using ui-grid single edit functionality. So I have cellNav and editOnFocus set to true. It basically achieves the expectation but while editing cells, the last edited cell remains selected (darker shade) . Also it takes a double click to bring such a cell to edit mode thereafter.

This do not make sense as a functionality. Found few post on SO regarding the same but could not figure out a solution from the library itself.

I think this needs to be fixed (I am not aware if it has already been). Is there a resolution for this??
