Console resources not found if WebMvcConfigurationSupport declared

[artemik]

Grails 3.2.11
Console 2.0.9

If in my java configuration I have a configuration class (even empty):

@Configuration
class MyConfig extends WebMvcConfigurationSupport {
}

at /console resources are not found and the console doesn't show up. All its static resources are 404.

I'd like to use this config class to configure MVC related beans (for example add custom message converters).

Is it grails or grails-console bug? Or it's not a bug and I'm just not allowed to use WebMvcConfigurationSupport classes in Grails projects?
