now the dialog root view has theApplicationrootView as parent to be able to access thens-root class which comply with css specs (for example to read root css variables)

I think it's more like a feature than a fix. Old docs state that you have to use.ns-modal for styling modal root view and children.
https://v6.docs.nativescript.org/ui/styling#root-views-css-classes

You still can. Ns-modal only apply to modals
But without that PR you can't access root CSS variables from a modal CSS. Which you would expect ( I think). I mean the rootview of application also is the root view for modals, bottom sheet...

I see your point but will this implementation work for the case when root view is a Frame? That class seems to have a special handling foreachChildView and it might be a problem:https://github.com/NativeScript/NativeScript/blob/main/packages/core/ui/frame/frame-common.ts#L538

UPDATED: The same applies to other views that can be used as root views.

@farfromrefug I use this and work finehttps://github.com/vallemar/nativescript-reordering/blob/main/src/app.css#L17-L38

@vallemar yes it does. But not when you start modifying them from yes. From what you have root and modal properties are actually not the same

@CatchABus it should not change anything. EachChild and parent are decoupled. Setting the parent does not imply it will be in eachChild. It won't !
