Panel doesn't inherit border defaults when added programmatically

When using Neptune or Crisp, there's a bug where if you programmatically insert a Panel inside another Panel that has a defaults configuration for border set to false, the inserted Panel will ignore the border policy and draw a border around its body.



I've created a fiddle to illustrate te problem: http://ift.tt/1IzRob4



When items are declaratively added to #lowerPanel, the border policy is respected. When adding a Panel dynamically, it is not (and so the panel has a border).

I've found that when I add a Container instead of a Panel, the inserted component does follow the no-border configuration, which in my opinion suggests a bug somewhere inside Panel.

In all the test cases the padding configuration is respected, only the border is ignored.



This bug does not appear when using the classic theme.
