title: Extjs Anchor Layout using offsets
body: <p>What is the offset configuration actually doing that makes panel 2 to show incompletely when the panel 1 is resized vertically?</p>
  
  <pre><code>Ext.onReady(function(){
      var myWin = Ext.create('Ext.window.Window',{
          height      : 300,
          width       : 300,
          layout      : 'anchor',
          border      : false,
          anchorSize  : 400,
          items       : [
              {
                  title : 'panel 1',
                  anchor: '-50, -150',
                  frame : true
              },
              {
                  title : 'panel 2',
                  anchor: '-10, -150', // how is this config working?
                  frame : true
              }
          ]
      });
      myWin.show();
  });
