Problem Description:
In a typical <grid>/<columns> zul set up. Attaching a <frozen> as a child of <grid> enables freeze-scrollbar.

Problem#1: When all the columns in the grid are fully visible in their intended widths, this scrollbar is scrollable.

Expected#1: The scrollbar shouldn't be scrollable

Problem#2: When browsers were set to a size smaller than the grid size, all the non-frozen columns width were adjusted accordingly, but the freeze-scrollbar doesn't get updated according to the new grid layout, i.e. users are able to scroll beyond the last column

Expected#2: The scrollbar should only scroll to the end of the last column in its adjusted width.

Note: I tried all combinations of "span", "sizedByContent", "hflex", "width" attributes combinations of <grid>, <columns>, <column> with no success.
