Doesn't parallel work with another process

[falsandtru]

In the following case,

gulp.task('watch', ['clean'], function (done) {
  seq(
    'ts:test',
    [
      'ts:watch',
      'karma:watch'
    ],
    done
  );
});

this parallel process works fine with karma-espower-preprocessor but this plugin doesn't.

    [
      'ts:watch',
      'karma:watch'
    ],

If another process is removed, it works fine.

    [
      'karma:watch'
    ],

That sounds like a bug. I will find my time to work on this. I'd appreciate if you could give me any idea about why that happens. Thanks!
