Can't do that. Gotta do one, with three layers passed in the first arg,
and that will only work in 2.8/trunk.

Safari 4 is whacked. The former is the expected behavior. This is
because browsers will not let us catch events through the top SVG
element on the lower level elements. As a result, we've extended the
SelectFeature control to be able to take efeatures from *all* layers and
put them in the same SVG element.

Yes, Because the GeoRSS class uses markers, and doens't have the same
behavior because no SVG is involved.

The clicks aren't getting there.
