  • Updated BadgeAdorner ZIndex to be relative to the adorned element so overlapping badge adornments have a ZIndex consistent with the adorned elements.
  • Fixed an issue where opening a new User Prompt without an explicit owner immediately after closing a window might throw an exception due to the closing window being used as the default owner.
