Unhandled `cobalt::task` prevents destruction of `asio::io_context`

Code:

#include <cstdio>

#include <boost/asio.hpp>
#include <boost/cobalt.hpp>

namespace asio = boost::asio;
namespace cobalt = boost::cobalt;

asio::awaitable<void> emptyAsioAwaitable()
{
  std::puts("Inside ASIO");
  co_return;
}

cobalt::task<void> emptyCobaltTask()
{
  std::puts("Inside COBALT");
  co_return;
}

void testCobalt()
{
  asio::io_context context;
  cobalt::spawn(context, emptyCobaltTask(), asio::detached);
  context.stop();
}

void testAsio()
{
  asio::io_context context;
  asio::co_spawn(context, emptyAsioAwaitable(), asio::detached);
  context.stop();
}

int main()
{
  std::puts("before ASIO test");
  testAsio();
  std::puts("after ASIO test");

  std::puts("before COBALT test");
  testCobalt();
  std::puts("after COBALT test");
  return 0;
}

Built on Windows 10 64-bit using MSVC 17.9.6 (cl version 19.39.33523 for x64) with following command:

cl /Femain.exe main.cpp /nologo /external:IC:\Users\chodorowskip\repo\deps\vc143\boost-1.85.0\include\boost-1_85 /std:c++20 /MD /Z7 /O2 /EHsc /D_WIN32_WINNT=0x0601 /W4 /external:W0 /link /PROFILE /LIBPATH:C:\Users\chodorowskip\repo\deps\vc143\boost-1.85.0\lib libboost_cobalt-vc143-mt-x64-1_85.lib

Gives following result:

before ASIO test
after ASIO test
before COBALT test
