[Vaadin 7] Issue with scrollbar

Hi All,

I’m facing the problem with the scrollbar when using vaadin 7. The problem is scrollbar always scroll to the top of dialog when I scroll down the dialog and select an item of the inside table. Please see screenshot enclosed for more detail - If I scroll the dialog as screenshot 2 (2.png) and select any item in the table the dialog will automatically scroll to the top of dialog as screenshot 1 (1.png).
Note: the problem was not happened when I used Vaadin 6.

I would be very appreciate if someone can fix this problem or provide me with any suggestion.

Thanks in advance
