SwiftUI bug! onKeyPress resets binding to initial state

BugRepro.swift

import SwiftUI

struct OuterView: View {
    @State var count: Int = 0
    
    var body: some View {
        VStack {
            MiddleView(count: $count)
                .onAppear {
                    count += 100
                }
        }
    }
}

struct MiddleView: View {
    @Binding var count: Int
    
    var body: some View {
        InnerView(count: $count)
        .focusable()
        .onKeyPress(.space) {
            count += 1 // will evaluate to 0 during first execution even after count has already been updated
            return .handled
        }
        .onTapGesture {
            count += 1
        }
    }
}

struct InnerView: View {
    @Binding var count: Int
    
    var body: some View {
        Text(String(count))
    }
}

If you tap the number, the count will increase from 100. If you press space, the count will increase from 0. Things behave as expected after a keypress handler has run at least once.
