Hover events on the lines themselves

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.

Inizia tracciando la gestione dell’hover di scattermapbox e il percorso del relativo evento di callback; l’issue non identifica file o test specifici. Confronta il comportamento esistente di point-hover con quello richiesto di line-hover e considera il lavoro completo quando il passaggio del mouse su una linea può attivare un evento, invece di poterlo fare solo passando sui punti che la compongono.
