Earth manipulator setMinMaxDistance() doesn't work well with setZoomToMouse()

[OlaRune]

When using a maximum zoom distance together with zoom to mouse

osgEarth::EarthManipulator* manipulator = new osgEarth::EarthManipulator();
manipulator->getSettings()->setZoomToMouse(true);
manipulator->getSettings()->setMinMaxDistance(0.0, 100000000.0);
viewer->setCameraManipulator(manipulator);

... and trying to zoom out farther than the max distance. The zoom function is limited as expected, however the new center point is recalculated and applied, which makes the map pan away in some direction.
