Description
A dash community user brought this up https://community.plot.ly/t/linking-scattermapbox-lines-to-other-data-with-callbacks/5449
They would like some type of event be fired when hovering over lines instead of just points:
I would also like to raise an appeal for maps of lines being treated as actual lines rather than collections of points. It seems like the callbacks are only firing above the component points, rather than over the line itself, which is confusing to an end user.

Research direction
Start by tracing scattermapbox hover handling and its callback event path; the issue does not identify specific files or tests. Compare the existing point-hover behavior with the requested line-hover behavior, and consider the work complete when hovering a line can fire an event rather than only hovering its component points.
