The tooltip shows which is great.
The connector line shows for many of the map locations, but not all.
The locations on the map that are lower on the page than the tooltip and directly below (not behind) the tooltop won't show the connector line.
See the attached screen shots.
The test (dup) URL of the map in use is here: https://www.thegoodstudy.org/GOOD/Parti ... -Sites-Dup
