Grouping rows disappear when there are lots of rows to group

[Luis Campuzano]

Issue:  Grouping rows disappear when there are lots of rows to group.  

When we scroll down and scroll back up, the grouping row is blank and a different color.

See screenshots on zip file:

1. When open the page and the Grid is loaded and had a lot of items that we need to scroll to see the other items that it doesn't show on the screen

2. We can see the stop: 4 with it items, and we can see there are others stops (Picture 1)

3. When we scroll down to where should be the Stop 1, it is blank and a different color, (Picture 2)

4. If we scroll up again, to see stop 4, the grouping row for that stop that was there, is blank and a different color. (Picture 3)

5. We assume that only change the color when it outside of the grid view and it doesn't refresh back.
