Game grid should not show focus square or highlights when focus is on buttons

Description
When using the keyboard to play Gnome Sudoku, if you press the right arrow while in the rightmost column, the focus changes to the "Clear Board" button. However, the game still displays the focus square and the row/column highlights (if enabled) from where the focus previously was.
I seem to inadvertently press right arrow too many times quite often. This means that suddenly the number buttons stop working for no obvious reason. I then need to look over at the "Clear Board" button, notice that it has focus, sigh, and press left arrow to return the focus back to the game grid.
The focus square and row/column highlights (if enabled) should be hidden whenever the focus leaves the game grid.
