debugging pytest with playwright subprocess fails

[orenherman]

hi all, i have a big complex test suite based on pytest that launches a browser and orchestrates it with playwright currently my settings for nvim-dap are:

{
  runner = 'pytest',
  python = '/Users/orenherman/.virtualenvs/debugpy/bin/python',
  dap = {
    python = { '-Xfrozen_modules=off', '--multiprocess', '--qt-support=auto' },
    console = 'integratedTerminal',
    justMyCode = false,
    stopOnEntry = true,
    subProcess = true,
  },
}

i can set breakpoints in the different entry points and it'll catch them, but once set inside the subprocess that orchestrates the browser (the actual test) - it will skip those and disconnect the debugger. i know this must be a debugpy issue (although i do manage to debut the subprocesses in vscode) but i wonder if i can get some guidance please? ** worth noting, that debugging with subProcess = false or just running the test works just fine ill try and post a small repo with playwright and pytest to reproduce

possible workaround - setting the pytest --numprocesses to 1, will result in 1 and the debugger will catch the breakpoint.

Would need a minimal reproduction.
