<div>For AppButtons I can access AppButton::style to change particular things about the style independent of the global Theme.</div>
<div>I need to center the text on NavigationBar::titleItem and I could do it by setting it from the global theme:</div>
Theme.navigationBar.titleAlignLeft = false
But I only want it to apply to a particular instance of a NavigationStack/NavigationBar.
It would be useful to have access to NavigationBar::style.
