[nativescript-ui-listview] Upgrade from 10.0.0.1 to 14.2.4 breaks my list

This only happens on iOS. Android is fine. Items overlap after the upgrade.

On v10:

On v14

and the relevant code (note the issue occurs in the "pot" template):

Start with the provided RadListView markup and the pot item template, then reproduce the overlap on iOS while comparing versions 10.0.0.1 and 14.2.4. Trace the list layout and item sizing behavior; done means pot items no longer overlap on iOS while the existing Android behavior remains intact.
