Referencing the action starts an elastic container build step even if the action itself is skipped

[porgabi]

The Elasticsearch action is conditionally called in a workflow, but even when it's not run, the container build step still runs. Here's an example for such a build:

The Elasticsearch action is referenced in the action.yml file found in this pull request, which is conditionally called in the build-and-test-orchard-core.yml file.

Is this normal behavior, or can it be prevented somehow? The container build step shouldn't run when the Elasticsearch setup step doesn't.
