I periodically receive a new "myData" string with the new items to show
and of course I cannot just re-run the js snippet above because it will
re-instantiate the same widgets.
I also tried to use list.destroyRecursive() and add a new one via js,
but I was in trouble with the ScrollablePane behavior.
Hence I'm wondering what is the right way to re-populate an
EdgeToEdgeStoreList with custom items.
