View randomly doesn't update iOS 17

[arnauddorgans]

Description

I have a ScrollView containing a LazyVStack with four views, each with its scope.
Randomly, one of the views is not updated.
When I add a tap gesture on the not updated view to print the state, the state prints correctly updated, but the update is not visible in the view.

    let store: StoreOf<DiscoverCategory>

    var body: some View {
        ScrollView { _ in
            WithPerceptionTracking {
                if store.hasError {
                    // Error sate placeholder
                } else if store.isEmpty {
                    // Empty sate placeholder
                } else {
                    content
                }
            }
            .padding(.vertical, Spacing.medium)
        }
    }

@MainActor
    private var content: some View {
        WithPerceptionTracking {
            LazyVStack(spacing: Spacing.huge) {
                // One of the following view is randomly not updated
                if store.showSubcategorySection {
                    SubcategoryListSectionView(store: store.scope(
                        state: \.subcategoryListSection,
                        action: \.subcategoryListSection
                    ))
                }
                ShowListSectionView(store: store.scope(
                    state: \.showListSection,
                    action: \.showListSection
                ))
                ProductListSectionView(store: store.scope(
                    state: \.productListSection,
                    action: \.productListSection
                ))
                ShowListGridSectionView(store: store.scope(
                    state: \.showList,
                    action: \.showList
                ))
            }
        }
    }

I have no runtime warning or nothing.

@arnauddorgans WithPerceptionTracking needs to be used wherever a "lazy"/@escaping closure is, which LazyVStack is. Try moving the WithPerceptionTracking into the lazy view:

 @MainActor
 private var content: some View {
-  WithPerceptionTracking {
   LazyVStack(spacing: Spacing.huge) {
+    WithPerceptionTracking {

Because this isn't a bug in the library I'm going to convert to a discussion.

[arnauddorgans]

I thought WithPerceptionTracking was useful only before iOS 17, and bad usage of WithPerceptionTracking will result in a runtime warning 🤔

[arnauddorgans]

@stephencelis I still have issues when moving WithPerceptionTracking even if I think it is useless in iOS 17 to do this because Perception is not used.
I think it is an issue, not a discussion :/

[arnauddorgans]

I think this is related to #2888

@arnauddorgans If you believe this is an issue please provide a full sample project that we can build and use. The code snippet above is just a view and doesn't compile without the supporting code.
