OTEL Context not being propagated to @Asynchronous component

[jvissers]

Environment Details

• Helidon Version: 4.1.4
• Helidon MP
• OpenJDK 64-Bit Server VM (build 23+37-2369, mixed mode, sharing)
• OS: Ubuntu 24.04.1 LTS

Problem Description

We want to propagate OpenTelemetry context to an @Asynchronous component, but it looks like no context is propagated. Span.current() reports Optional.empty().

Confirmed, MP Async has one default Helidon context unaware executor which can't be configured in MP.
