layoutFileBrowserComponent not getting called in custom look and feel class

Is there anything special I have to do to get layoutFileBrowserComponent to get called in my custom LookAndFeel class. I'm inheriting from LookAndFeel_V3 and drawFileBrowserRow gets called but layoutFileBrowserComponent never does.

It gets called directly from FileBrowserComponent::resized(), so it should always happen. Maybe just a typo or something in your code?
