Should Visual Studio "Code Cleanup" format gherkin files?

Question

Hello fellow programmers!

I started to use Code Cleanup Visual Studio feature recently, but have noticed something inconsistent.

We are using Reqnroll (formerly known as Specflow) in our project together with official Reqnroll plugin for VS. When I navigate to gherkin file (*.feature) and format document manually it works like a charm. However, if I run Code Cleanup, the code is not formatted, even though I have it configured in my Code Cleanup Profile:

Can someone tell me why this is not working? Maybe I am missing some additional configuration? Or my assumptions are wrong and it is by design? Many thanks for your help in advance :)
