Trying to diagnose why my scrollview is dropping frames when using core data

Dropped-frames.swift

// See bottom of gist for things I've tried, recommendations welcome

// Core data ScrollView:
//
// For some reason, the top bounce-back of the scroll
// here drops frames and looks horrible.

NavigationView {
  ScrollView {
    VStack(spacing: 8) {
    // Core data loop using a sectioned fetch request
      ForEach(sections) { section in
        // Section headers
        HStack {
          Text("\(section.id)")
          Spacer()
          Text("\(section.count)")
        }
        // Individual entries
        ForEach(section) { entry in
          Button {
            currentEntry = entry
            entryPopOverVisible.toggle()
          } label: {
            // Nothing fancy happening in this view.
            // Even dummy text here instead of a view passing data
            // into results in the same dropped frame madness
            EntryCell(entry: entry)
          }
        }
      }
    }
  }
  .navigationTitle("Test")
  .navigationBarTitleDisplayMode(.inline)
}

// Dummy data ScrollView
//
// If I use the exact same layout (minus the core data)
// stuff, the bounce-back animation at the top of the
// scroll is smooth (as it should be)

NavigationView {
  ScrollView {
    VStack(spacing: 8) {
    // 500 dummy data views
      ForEach((1...500), id: \.self) {
        Text("\($0)")
          // Some basic styles to make the cells full width and larger
          .padding()
          .frame(maxWidth: .infinity)
      }
    }
  }
  .navigationTitle("Test")
  .navigationBarTitleDisplayMode(.inline)
}

// Steps I've tried:
//
// 1. Using dummy data - NO frames drop
// 2. Commenting out the HStack section headers - frames drop
// 3. Replacing `EntryCell(entry: entry)` with `Text("Hello")` - frames drop
// 4. Using a `@FetchRequest` instead of a `@SectionedFetchRequest` (and thus a single ForEach) - frames drop
