Hello,
while experimenting with gritstack.js I noticed an unpleasant effect. I was able to recreate it with one of the demos and made a recording:

How to recreate:
If you resize the window to a point, where the grid ends at the bottom of the window, the scroll bar constantly appears and disappears by itself until the window is resized again. This also happens when the grid grows or shrinks to that size by adding/removing items.

Regards
