UITabBarItem(s) generated for UITabBarController have their titles overwritten by the page <title>

[aquilarafa]

After a page visit any UITabBarItem title is changed to match the page <title>.

Since each tab is a TurboNavigationController it appears that after setting the title programmatically

viewController.title = title(from: properties)

The UITabBarItem title is also changed.
