When lazy loading imagemaps lazy loader doesn't set usemap attribute, hence breaking image maps.
How to reproduce:
Go to some article that use imagemap (the image shouldn't be small image, and not in the first section - lazy loading is done only for large images) and compare the desktop and the mobile versions.
- The usemap attribute is copied across as data-usemap in the placeholder
- The usemap attribute is copied across when JS loads the image
