Remove from this patch.

Ok, I will create a separate one for this. And actually after making the widget
ACTIVATABLE_NO, it doesn't crash here anymore, so we can submit the two patches
in any order.

   if (switches::IsTextInputFocusManagerEnabled()) {
     FocusManager* focus_manager = GetWidget()->GetFocusManager();
     delegate_->OnKeyEvent(event);
