Simple example does not do column/row layout under WidgetKit

[t9mike]

This one is pretty odd. This simple WidgetKit example:

import SwiftUI
import ExyteGrid
import WidgetKit

struct GridIssue2View: View {
    var body: some View {
        Grid(tracks: [
            .fit, // label
            .fit, // value
        ], spacing: 3)
        {
            Text("A")
            Text("B")
            Text("C")
            Text("D")
        }
    }
}

struct GridIssue2View_Previews: PreviewProvider {
    static var previews: some View
    {
        GridIssue2View()
            .previewContext(WidgetPreviewContext(family: .systemSmall))
    }
}

Does not do column/row layout in preview mode:

But when placed in view for real widget, it renders OK in preview. Also I could place within ZStack to fix:

struct GridIssue2View: View {
    var body: some View {
        ZStack
        {
            Grid(tracks: [
                .fit, // label
                .fit, // value
            ], spacing: 3)
            {
                Text("A")
                Text("B")
                Text("C")
                Text("D")
            }
        }
    }
}

Similar preview example under iOS is fine. Perhaps related to ScrollView change?

iOS:

import SwiftUI
import ExyteGrid

struct GridIssue2View: View {
    var body: some View {
        Grid(tracks: [
            .fit, // label
            .fit, // value
        ], spacing: 3)
        {
            Text("A")
            Text("B")
            Text("C")
            Text("D")
        }
    }
}

struct GridIssue2View_Previews: PreviewProvider {
    static var previews: some View {
        GridIssue2View()
    }
}

To support a preview for Grid I had to apply some kind of hack (ForEach+GridViewsContaining.swift:46-68 and GridGroup.swift:20-30).
Looks like it doesn't work for widgets.
