Tab Panels within tab panels

I have a main tab panel with one tab that will display a form that has another tab panel. This main tab has a value of “Defaults” which uses a variable called tabpanelone in the Data Field in the Tab Panel Options section. This main tab will display a form that has another tab panel which uses the variable tabpaneltwo in the Data Field in the Tab Panel Options section. When I select the tab “Defaults” in the main tab panel and then select a tab in the “sub tab panel” the tab “Defaults” in the main tab panel becomes unselected…not highlighted. Is this expected behavior?

Yes, that is what it does, you can see this in one of the Site License panels. I guess this could be considered a pretty minor cosmetic issue. Other than this, the nested tab panels do work correctly.
