Fire onresizestop after complete resizing

When resizing a widget, the dimensions snap to the grid after the handle is released. This is great. :)

However, it seems that onresizestop() is triggered before that process is finished so if you try to get the widgets dimension, you get them 'wrong'.
Is there a way to get an event that is triggered after the full resizing process?
