Spring Cloud Openfeign FeignCircuitBreakerInvocationHandler removes RequestAttributes from main invoking context

FeignCircuitBreakerInvocationHandler removes RequestAttributes and makes it null in invoking context.

Bug exists at least in 3.0.3 (in version 3.0.2 problem doesn't occur ) https://github.com/spring-cloud/spring-cloud-openfeign/blob/0c1ab36fe1ebe0a8bc003fd23c8c20a4381e50c0/spring-cloud-openfeign-core/src/main/java/org/springframework/cloud/openfeign/FeignCircuitBreakerInvocationHandler.java#L118

    private Supplier<Object> asSupplier(final Method method, final Object[] args) {
        final RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
        return () -> {
            try {
                RequestContextHolder.setRequestAttributes(requestAttributes);
                return this.dispatch.get(method).invoke(args);
            }
            catch (RuntimeException throwable) {
                throw throwable;
            }
            catch (Throwable throwable) {
                throw new RuntimeException(throwable);
            }
            finally {
                RequestContextHolder.resetRequestAttributes(); // that is the problem 
            }
        };
    }

Example

....
public void someMethod(){
  RequestContextHolder.currentRequestAttributes() // that returns not null
  someService.externalInvokeWithFeign();
  RequestContextHolder.currentRequestAttributes() // that returns null
}
...

Is removing a line of code without careful consideration?
