Rubymine "Automatic Upload" does not sync unversioned files

Using RubyMine 2019.3 on Windows 10 v1909. I have enabled the "Automatic Upload (on explicit save)" option:

This feature only works with local changes in the "Default Changelist". Changes in the "Unversioned files" are not automatically synced with the remote host.

Steps to reproduce:

1. Set up a deployment configuration
2. Enable "Automatic Upload (on explicit save)"
3. Create a new file and make some changes.

Expected behaviour:

• the newly created file is uploaded and kept in sync with the remote version.

Actual behaviour:

• the newly created file is not uploaded and is not kept in sync with the remote version.
