I think that flash of light, whatever it is, is disabling the shield.
True, it could go either way, I don't think Iceheart wants to see Ishgard destroyed though, I got the feeling that she wants peace, instead of Ishgard being decimated, though perhaps that could be her way of getting 'peace'. Good point about the barrier possibly being there all along, it would make sense, given the constant attacks the city suffers.
