pyhocon does not handle backslashes the same way json does

[joelgrus]

In [1]: import json, pyhocon

In [2]: single = r'{"a": "b\.c"}'

In [3]: double = r'{"a": "b\\.c"}'

In [4]: json.loads(single)
---------------------------------------------------------------------------
JSONDecodeError...

In [5]: json.loads(double)
Out[5]: {'a': 'b\\.c'}

In [6]: pyhocon.ConfigFactory.parse_string(single)
Out[6]: ConfigTree([('a', 'b\\.c')])

In [7]: pyhocon.ConfigFactory.parse_string(double)
Out[7]: ConfigTree([('a', 'b\\\\.c')])

In [8]: json.dumps(json.loads(double))
Out[8]: '{"a": "b\\\\.c"}'

In [9]: json.dumps(json.loads(double)) == double
Out[9]: True

In [10]: json.dumps(pyhocon.ConfigFactory.parse_string(double))
Out[10]: '{"a": "b\\\\\\\\.c"}'

In [11]: json.dumps(pyhocon.ConfigFactory.parse_string(double)) == double
Out[11]: False

I looked at the HOCON documentation and I couldn't find explicit guidance, but I'd expect that my single example would be invalid HOCON (it's invalid JSON?) and that my double example would get parsed the same way that json.loads does it?

Does this have a fix?
