I'm not really sure what is going on, but catching
wx.aui.EVT_AUINOTEBOOK_PAGE_CHANGING and then vetoing the event if the
TopLevelParent is not active helped. In code:

class MyAuiNotebook(wx.aui.AuiNotebook):
    def __init__(self, *args, **kwargs):
        super(MyAuiNotebook, self).__init__(*args, **kwargs)
        self.Bind(wx.aui.EVT_AUINOTEBOOK_PAGE_CHANGING, self.onPageChanging)

    def onPageChanging(self, event):
        if self.GetTopLevelParent().IsActive():
            event.Skip()
        else:
            event.Veto()
