Grid items dissapears

Hi, I’ve got a Tabs component and a layout that is refreshed with new content every time the user clicks a Tab. The content usually is a grid. When the grid is to large and I scroll it down to the end and then click another tab and go back to the previous tab (where that scrolled grid is), all the data of the grid disappears. If I do the same without scrolling it down to the end everything works fine. Is this a know bug?
