Fix issue where introspecting within a LazyVStack would silently fail

[crayment]

I ran into the issue described in #140 and the fix described worked for me. We are using introspectScrollView within a LazyVStack and without this fix introspect fails when the scrollview is "below the fold". In our case we have nested ScrollViews something like this:

ScrollView(.vertical) {
    LazyVStack {
        ScrollView(.horizontal) {
        }
        .introspectScrollView {
            // This fails when the horizontal scrollview is below the fold.
        }
    }
}

We have the same issue, when can we expect the PR to get merged?
