to make resetting smoother

Please open the following web page. In the rectangle, click the 'display' button, letters would appear in the cells. Then click the 'reset' button.  Letters in the  top cells would disappear.  Then there is an interval during which nothing happens.  Then letters in the bottom cells disappear.

I like to see that resetting of the letters in the bottom cells takes place immediately after that in  the top cells.  There is not stop between them.

<p><b>Problem</b>: In preceding rectangle, clicking 'Display', words will appear in the cells. Then clicking 'Reset', the word 'TAMPA' will go away first. Then nothing happens for a short time. Then the word 'FLORIDA' goes away. I like to see that after the 'TAMPA' goes, the 'FLORIDA' starts to go immediately rather than waiting for a short time.
