Highlights array not present when there is no Measures DataRoll

I'm having some issues with locating the highlighting array. I have built a visual with two Grouping DataRoles and one Measure Data Role (the measure roll may or may not be filled). I can observe the highlights array when the Measure DataRole is filled with data, however, when it is empty (the visual will still build when empty) there is no way to access the highlight array that resides in the categorical.values location as it is null at this level. I've tried to create a dummy class inside the powerbi.extensibility.visual module to use a filter to get a filtered value that can be accessed from the main visual building class, but predictably, I just ended up filtering all the data coming. Is there any way to get around this?

The highlighting array is specified if and only if Measure field is filled.

This is default and expected behavior of Power BI.

Is there a way to get the highlight array any other way? Or, is there a way to implement two separate IVisual classes within one extensibility module? I basically have a hierarchy table with no measure data and want to highlight an entry based on a dropdown menu.

As far as I know, there aren't other ways unfortunately.
