title: ag-grid: setting grid option 'suppressHorizontalScroll' after creation has no effect
body: <p>How do I apply suppressHorizontalScroll (or any grid property I guess) after grid creation?</p>
  
  <p>I'm trying to apply a grid footer using <a href="https://www.ag-grid.com/javascript-grid-aligned-grids/exampleAlignedFloatingFooter.html" rel="nofollow noreferrer">aligned grids</a> on an already created grid but it seems like setting <code>suppressHorizontalScroll</code> on the main grid doesn't have any effect. Still seeing the horizontal scrollbar.</p>
  
  <p>If it matters, the grid itself is created via the angular 1 directive.</p>
