Title: FIX: Sortable plugin bug when connecting a scrollable list with one in a fixed position div

I've modified the _contactContainers function so that it considers more criteria when selecting the container for interaction. In addition to the existing logic of selecting the "innermost" container, the function will now prefer lists housed in a fixed position element.

This fixes #7882 – Sortable list connected to a list in a "position:fixed" does not drag properly if the two lists overlap.
