Unit test failure in multi-currency org

[stohn777]

Describe the bug

When deployed into an org having multi-currency enabled, the fflib_SObjectSelectorTest.testPolymorphicSelectWithRelatedType test fails with the exception "fflib_QueryFactory.InvalidFieldException: Invalid field 'CurrencyIsoCode' for object 'Group'".

To Reproduce

1. Create a scratch org from the project's only definition file.
2. In the org's Company Information, enable multi-currency.
3. Push the source to the org.
4. Run all tests.
5. Note that all tests pass except for fflib_SObjectSelectorTest.testPolymorphicSelectWithRelatedType with the following exception.

fflib_QueryFactory.InvalidFieldException: Invalid field 'CurrencyIsoCode' for object 'Group'
Class.fflib_QueryFactory.getFieldPath: line 131, column 1
Class.fflib_QueryFactory.selectField: line 224, column 1
Class.fflib_SObjectSelector.configureQueryFactoryFields: line 388, column 1
Class.fflib_SObjectSelectorTest.testPolymorphicSelectWithRelatedType: line 486, column 1

Expected behavior
In a multi-currency org (as well as a single-currency org), all tests should pass.

Version
Latest version of master as of 2022-12-22 (commit: fbe6df4).

I just encountered the same error once running the tests. Do we have any ETA when this will be fixed?
