cmd.exe is expected to be available on the PATH in WSL

When I try to use open from WSL, it fails to open URLs

$ npx open-cli http://google.com
npx: installed 82 in 9.186s
events.js:291
      throw er; // Unhandled 'error' event
      ^

Error: spawn cmd.exe ENOENT

  code: 'ENOENT',
  syscall: 'spawn cmd.exe',
  path: 'cmd.exe',
  spawnargs: [ '/s', '/c', 'start', '""', '/b', 'http://google.com' ]
}

I'm assuming this is because there is no browser or it's otherwise WSL related.

I misread the error. This fails because open expects cmd.exe to be available through the PATH, I guess. On my system I have appending of the Windows PATH disabled.

Given how this is a valid configuration, maybe something can be done to handle it?
