Lazy loaded images: Copy `usemap` attribute for image maps
Open, NormalPublic3 Story Points


Note: There are several lazy loaded images bugs T207929, T199351, T209183. We'll probably want to fix these 3 bugs together.

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.



Acceptance criteria

  • The usemap attribute is copied across as data-usemap in the placeholder
  • The usemap attribute is copied across when JS loads the image
