geoxml3 kml polygon tooltip on mouseover instead of click

问题

I need an working example or a solution for hovering a kml polygon and showing the info balloon - instead of doing it on click. Is it doable?

For example, on this map, instead of showing the info balloon on click, doing it on mouse over:

Obs.: my kml file has additional info inside Placemark => ExtendedData (if that helps in any way).

tks :)

Here is an example that uses InfoBubble for the "tooltip" (only handles polygons):
