add new error banner module for showing users js errors this ensures it's reusable by other components, and easier to unit test by isolating the separate concerns note: this is not in Modules since that's designed for classes that are then bound to an element in the DOM as indicated by a data-module attribute. This will just live at the window.GOVUK level since we want there to only ever be one `.banner-dangerous` warning. 2021-07-20 12:14:10 +01:00
