Header in List (iOS 15) is taller than it should be

Question

I just updated to Xcode 13 and iOS 15 and I'm experiencing weird glitch that I cannot figure out how to fix. I have a List with header. The header has fixed height of 44.0. The extra space isn't there on iOS 14.

Xcode	App

List:

var body: some View {
    List {
        pendingRequestsSection
        visitedRequestsSection
    }
    .listStyle(InsetGroupedListStyle())
}

// Sections

private var pendingRequestsSection: some View {
    Section(
            content: {
                if viewModel.pendingRowModels.isEmpty {
                    noRequestsRow
                } else {
                    ForEach(viewModel.pendingRowModels, content: requestRow)
                }
            },
            header: {
                ListReloadView(
                    isLoading: $viewModel.isLoading,
                    lastFetchDate: $viewModel.recentFetchDate,
                    action: viewModel.reloadTapped
                )
            }
        )
    .textCase(nil)
}

...

Header:

var body: some View {
        Button(
            action: action,
            label: { buttonContent }
        )
        .frame(height: 44.0)
    }

    // Helpers

    private var buttonContent: some View {
        HStack(alignment: .center) {
            Spacer()
            lastFetchDate.flatMap(timeLabel)
            reloadLabel
            Spacer()
        }
    }

    private var reloadLabel: some View {
        Text(isLoading ? "Loading..." : "Reload")
            .font(.system(size: 12.0, weight: .semibold))
            .foregroundColor(UIColor.accent.color)
            .multilineTextAlignment(.center)
    }

Any ideas? I'm really pissed with this iOS+Xcode release. So many things broke suddenly. Smh. Thanks in advance!
