class with parent selector not working

[naoliv]

Or I need to sleep better or using a class with a parent selector isn't working.
Example:

way[highway] > node { set .is_in_highway; }

node.is_in_highway < area[!highway] {
        throwWarning: tr("you should not attach the area to the highway");
}

This should match areas that share a node with highways.

Complementing. This matches the shared node (but I would like to match the areas instead, like the first MapCSS):

way[highway] > node { set .is_in_highway; }

area[!highway] > node.is_in_highway {
        throwWarning: tr("you should not attach the area to the highway");
}
