Wrapper extension leads to unknown properties

VSCode Quarkus Extension 1.5.0

I'm using the Quarkus wrapper extension quarkus-openshift inside my pom.xml which brings implicit the extensions quarkus-kubernetes and quarkus-container-image-s2i.

   ...
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-openshift</artifactId>
    </dependency>
   ...

In my application.properties file the properties of those implicit extensions are marked as unknown (yellow underlined). My expected behavior would be that all properties of such implicit extensions are known properties too.

# marked as unknown
quarkus.s2i.base-jvm-image=registry.access.redhat.com/ubi8/openjdk-11
quarkus.s2i.base-native-image=quay.io/quarkus/ubi-quarkus-native-binary-s2i:20.0.0
quarkus.s2i.native-arguments=-Xms8M -Xmx8M -Xmn8M

# known
quarkus.kubernetes-client.trust-certs=true
# marked as unknown
quarkus.kubernetes.deployment-target=openshift

# marked as unknown
quarkus.openshift.expose=true
quarkus.openshift.labels.app=quarkus-demo

If I explicit add those extensions to the pom.xml everything work fine again.

   ...
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-openshift</artifactId>
    </dependency>
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-kubernetes</artifactId>
    </dependency>
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-container-image-s2i</artifactId>
    </dependency>
   ...

Reproducable with my demo project:
