Describe the bug: I started using VEGA to create visualizations in KIBANA.
When trying to visualize a NxM matrix, which exceeds the size of the screen, there was no vertical or horizontal scroll bars.

Steps to reproduce:

1. In KIBANA create a new VEGA visualization
2. create any visualization that exceeds screen size
3. example:
   {
   "$schema":"https://vega.github.io/schema/vega/v3.json",
   "autosize":"none",
   "width":1600,
   "height":1600
   }

Expected behavior: horizontal and vertical scroll bars should appear
