Describe the bug

When injecting multiple microprofile metrics into a Quarkus managed bean using constructor injection, only the first such metric has the expected "scope=application" tag. Simply changing the bean to use field injection instead of constructor injection works around this bug.

Expected behavior

Microprofile metrics spec states that metrics should include a "scope" tag.

Actual behavior

The first microprofile counter injected into the constructor has the "scope" tag, but subsequent metrics injected this way lack the "scope" tag.

How to Reproduce?

microprofile-metric-tags-ctor-injection.tar.gz

The attached project constructor injects two microprofile counters.

@Path("/hello")
public class GreetingResource {

  private final Counter first;
  private final Counter second;

  @Inject
  public GreetingResource(
      @Metric(name = "first-counter") final Counter first,
      @Metric(name = "second-counter") final Counter second) {
    this.first = Objects.requireNonNull(first);
    this.second = Objects.requireNonNull(second);
  }

the QuarkusTest included in the project fails, because the second counter lacks the "scope" tag.

java.lang.AssertionError: Expected to find a tag with key 'scope' on counter MeterId{name='second-counter', tags=[]}
