lineSpacingSize is ignored when added as conditionalStyle

[samverner18]

    <style name="myStyle" fontSize="5">
        <conditionalStyle>
            <conditionExpression><![CDATA[true]]></conditionExpression>
            <style fontSize="15">
                <paragraph lineSpacing="Proportional" lineSpacingSize="5.0"/>
            </style>
        </conditionalStyle>
    </style>
    <queryString>
        <![CDATA[]]>
    </queryString>
    <detail>
        <band height="300" splitType="Stretch">
            <staticText>
                <reportElement style="myStyle" x="0" y="0" width="280" height="300" uuid="f5d29334-852e-46fc-8ff8-3b162f356d45"/>
                <text><![CDATA[Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

Adding lineSpacing and lineSpacingSize to a text-area directly works.

Adding lineSpacing and lineSpacingSize to a text-area via style works.

When lineSpacing and lineSpacingSize are as within a valid conditionalStyle -> lineSpacingSize is ignored completely See example above. Is this a bug? How can I convince jasper to use lineSpacingSize within a conditionalStyle?

Any help/pointer is greatly appreciated

Thanks
