I’ve noticed that behavior with Page Includes in general. So if you have two page includes separated into tabs, the first one will load on click, second one will load on click, but if you toggle between the two after that both disappear.
One thing i’d add to wizard navigation issues is clicking the 1-2-3 icons doesn’t evaluate the “Next” actions. So someone could just click 2 without the action sequence for 1->2 occurring.
