Fix: Compatiblity issue with jQuery 1.x when scrollCollapse is used a…

…nd the window forces the browser to scroll horizontally.

- In that situation the height of the DataTables container would be the height of the scrollbar. jQuery 3.x doesn't use the
  scrollbar height, returning 0, while 1.x returned 15 (or whatever for your platform).
- Solution is to remove jQuery there and just use clientHeight
