How can I pass OrderedDict in solid's config schema?

How can I pass an Ordered Dict in Dagster solid's config schema?

The simple thing:

from dagster import solid, execute_solid, Field


@solid(config_schema={'my_dict': Field(dict, is_required=True)})
def test_ordered_dict(context):
    print('\n\n>>>>>>>>>>>>>>>>>>>>>>>>>>>')
    print(context.solid_config['my_dict'])
    print('<<<<<<<<<<<<<<<<<<<<<<<<<<<\n\n')


for i in range(20):
    execute_solid(test_ordered_dict,
                  run_config={
                      'solids': {
                          'test_ordered_dict': {
                              'config': {
                                  'my_dict': {
                                      'a': 1,
                                      'b': 2
                                  }
                              }
                          }
                      }
                  })

doesn't work. Executing this on Windows 10 consistently gives

>>>>>>>>>>>>>>>>>>>>>>>>>>>
{'b': 2, 'a': 1}
<<<<<<<<<<<<<<<<<<<<<<<<<<<

On Linux, it sometimes switches them and this doesn't work for me.

How can I pass collections.OrderedDict in the config schema, so that the entries in the dictionary are ordered exactly as I passed them in the schema?

This is unexpected behavior and I was able to repro, looking in to it.
