Not seeing all test results in Run Window when using RSpec/example_steps

I have been using RubyMine with RSpec for some time and have recently tried the Gem rspec/example_steps for a project where the syntax provided by rspec/example_steps is more appropriate (https://github.com/railsware/rspec-example_steps)

If I run the tests from the command line (using 'rspec myprog_spec.rb --format documentation') I get all of the test results:

e.g.

Connecting to OPC Server Context
  Successful connection Steps
    Given disconnected from OPC Server
    When connect request sent
    Then should connect

        
However when I run the tests inside of RubyMine I only see the context and Steps and not the Given/When/Then.

e.g.

Test Results
  Connecting to OPC Server Context
    Successful connection Steps

I took a quick look at the example_steps source code and it appears to be registering the rspec formatters correctly.

Can RubyMine work with custom RSpec formatters or is it tied to the base formatter?
