Paged ScrollView loses page alignment when resized on iOS 27

A paged ScrollView loses its page when the window is resized on iPadOS 27:

ScrollView(.horizontal) {
    HStack(spacing: 0) {
        ForEach(pages) { page in
            PageView(page).containerRelativeFrame(.horizontal)
        }
    }
    .scrollTargetLayout()
}
.scrollTargetBehavior(.paging)
.scrollPosition(id: $selection)

Expected: the selected page stays edge-aligned after the resize (as TabView(.page) does).

Actual:

• The content offset is preserved in points, not pages — the view rests between pages.
• scrollPosition(id:) writes nil during the resize, so the selection can't be recovered from the binding.
• Both .paging and .viewAligned are affected.

Repro project (broken ScrollView, TabView control, and workaround side by side, with live instrumentation): https://github.com/katebrr/PagedScrollResizeLab

Why not TabView(.page): it has no API for scroll position/progress observation (our analytics depend on it), inter-page spacing, partial-width peeking pages, or pausing the swipe mid-gesture.

Workaround (Workaround/View+ScrollPositionResize.swift in the repo): restore the last non-nil selection via scrollTo one Task.yield() after the resize. Works, but lands a frame late and relies on undocumented behavior.

Questions:

1. Is this behavior intended, or a bug?
2. Is there a supported way to keep a paged ScrollView anchored to its page across resizes?
3. Is there a more robust formulation than scrollTo after Task.yield()?
