@srambach updated, changed the __item-action__action vars to __action after moving the .#{$data-list}__action {} block to the root instead of being nested in .#{$data-list}__item-action__action {}

Backstop report reports no failures compared to the last backstop run - backstop-data-list-7.10.24.pdf
