问题
I have a listbox(JumpListBox) with ~500 items.
Listbox template is a grid which have two columns - checkbox and image;
To reproduce problem: I've checked two items, then I do scrolling, then I can see that checkbox not corresponding to item which was selected. When I do scrolling back to the item I was selected I see that items are not selected, but other items was selected.
I recorded a video and you can see a problem.
