Memory leak when adding my app as Host Application

[adirburke]

I am getting a memory leak as soon as I add my app as a Host Application, even if the test is now using the code form the App

import XCTest
import ViewInspector
import SwiftUI
import Combine


public protocol TestProtocol {}
public final class TestSpy : TestProtocol {
    public init() {}
}

@available(iOS 13.0, macOS 10.15, tvOS 13.0, *)
struct TestView2: View {
    let value : TestProtocol
    
    @State private(set) var flag: Bool
    let publisher = PassthroughSubject<Bool, Never>()
    let inspection = Inspection<Self>()
    var didAppear: ((Self) -> Void)?
    
    var body: some View {
        Button(action: {
            self.flag.toggle()
        }, label: { Text(flag ? "true" : "false") })
        .onReceive(publisher) { self.flag = $0 }
        .onReceive(inspection.notice) { self.inspection.visit(self, $0) }
        .onAppear { self.didAppear?(self) }
    }
}

@available(iOS 13.0, macOS 10.15, tvOS 13.0, *)
final class Inspection<V>: InspectionEmissary {
    let notice = PassthroughSubject<UInt, Never>()
    var callbacks = [UInt: (V) -> Void]()
    
    func visit(_ view: V, _ line: UInt) {
        if let callback = callbacks.removeValue(forKey: line) {
            callback(view)
        } else {
            assertionFailure()
        }
    }
}

extension XCTestCase {
    func trackForMemoryLeaks(_ instance: AnyObject, file: StaticString = #filePath, line: UInt = #line) {
        addTeardownBlock { [weak instance] in
            XCTAssertNil(instance, "Instance should have been deallocated. Potential memory leak.", file: file, line: line)
        }
    }
}

final class TestingSomething: XCTestCase {

    @MainActor
    func testMemoryLeak() async throws {
        let spy = TestSpy()
        trackForMemoryLeaks(spy)
        let sut = TestView2(value: spy, flag: false)
        try await  ViewHosting.host(sut) {
            try await sut.inspection.inspect { view in
                let text = try view.implicitAnyView().button().labelView().text().string()
                XCTAssertEqual(text, "false")
                sut.publisher.send(true)
            }
            try await sut.inspection.inspect { view in
                let text = try view.implicitAnyView().button().labelView().text().string()
                XCTAssertEqual(text, "true")
            }
        }

    }

}

The Host Application is set and I get the memory leak, if I remove it I dont get it

If I comment out the inspection.inspect code it also doesnt leak
