Long lines in interfaces inside structs are not broken down

[noomly]

Golines doesn't do anything when ran on the following piece of code:

type MyStruct struct {
	LongInterface interface {
		SuperLongFunctionName(anArgument string, anotherReallyLongArgument string, superDuperLongArgument string, definitelyTheLongestArgument string) error
	}
}

My expectation was for it to format it this way:

type MyStruct struct {
	LongInterface interface {
		SuperLongFunctionName(
			anArgument string,
			anotherReallyLongArgument string,
			superDuperLongArgument string,
			definitelyTheLongestArgument string,
		) error
	}
}
