When resizing a grid-stack-item with the resize method, the item cannot have a bigger width if it is at the extreme right of the gridstack container. It seems like the container is limiting the increase of width of the grid-stack-item.

Basically, the resize method seems to always resize the width toward the right of the object but the container is limiting that operation. When the grid-stack-item is at the far right of the container, the grid-stack-item should resize the width toward the left instead.
