@3phase Also the ChangeLog should be updated with the new Input for the highlight directive and a test for that new input should be added.

• When there is paging and pinning is set to bottom items do not highlight that are in the unpinned area and are not on page 1.

  Steps:

  1. Pin a row when pinning is to bottom
  2. Search for an item that is on page different from the first.
     Result: The search scrolls to the item but it is not highlighted

@skrustev, thanks for remarking that issue, I think it's resolved now.
