I trapped into this, too.

        <Texture name="Highlight" textureFile="EsoUI/Art/Miscellaneous/listItem_highlight.dds" alpha="0" level="1" virtual="true">
            <AnchorFill />
            <TextureCoords left="0" right="1" top="0" bottom=".625" />
        </Texture>

You can take a look to LibAddonMenu-2.0.lua, too:
Search for:
ZO_ScrollList_EnableSelection(addonList, "ZO_ThinListHighlight", addonListRow_Select)
