Possible CSS style propagation anamoly

In the following FXML example, the style set on the foo label is propagated to the bar label. Is this the expected result, given that the scene graph containment path is the same for both labels? [VBox->HBox>Label]

The issue does not occur when the scene graph containment path is different (e.g. the "foo" label is in a VBox)

<VBox fx:controller="stylepropagationissue.Sample"

        <Label text="Foo" style="-fx-font-size: 40pt;"/>

        <Label text="Bar" />
