Modifiers don't apply to multi-element views correctly.

Comparing the following snippet between Mac and Linux, Mac shows a border around each child, while on Linux a single border is drawn around them together:

VStack {
 ForEach(1..<5) { i in
 Text("Child \(i)")
 }.border(Color.red)
}

The same can be observed when using a view that has multiple top-level children in its body.
